Temperature and heat are two distinct quantities. Heat is a type of energy that flows from a hot to a cold body, which is how it differs from temperature. In joules, it is mostly measured. The degree of hotness or coldness is called its temperature, and it is measured in Kelvin. Further, you will find out what is the greatest amount of heat when warming 100 grams of ice. Also, check out the greatest value for liquid water and whether temperature a measure of the amount of heat stored in a substance is true or not. 

1. What is the Greatest Amount of Heat when warming 100 Grams of Ice?

Converting 100 grams of ice into steam generates the greatest amount of heat when warming 100 grams of ice necessary to evaporate the water.

First, we need to find the heat required to melt the ice (convert ice to water) and then add it to the quantity of heat raised while changing water from its normal state to steam to get the value of total heat transferred,

So, the heat required to melt 100 grams of ice is,

Q1 = m × Hf  = 100 × 334 = 33400 J. [where Latent heat of fusion Hf = 334J/g]

Next, let’s calculate the amount of heat generated (convert water to steam) using the formula,

Q2 = m × C × ΔT

Q2 = 100 × 4.18 × (100 − 0), 

Q2 = 41800 J

  • where  C = the specific heat capacity of water =  4.18 J/g/°C
  • Q = Quantity of heat transferred 
  • m = mass of the object
  • ΔT = resulting temperature difference
  • The temperature of ice is considered 0 degrees Celsius and the boiling water (steam) is 100 degrees Celsius.

Therefore, the greatest amount of heat when warming 100 grams of ice is

Q1 + Q2 = 3400 + 41800 = 75200 J = 75.2 KJ.

NOTE: This situation doesn’t account for heat dissipation in the surrounding environment. (See How Long does Gas take to Evaporate?)

2. Is Temperature a Measure of the Amount of Heat stored in a Substance?

No, the temperature is not a measure of the amount of heat stored in a substance. It is the measure of the kinetic energy of the molecules of a substance. Heat is expressed in both calorie and metric units. (See What is the Temperature of Water at Room Temperature?)

3. What is the Greatest Value for Liquid Water?

Besides the greatest amount of heat when warming 100 grams of ice, note that the greatest value for liquid water is the latent heat of the vaporization of water, which is a physical property of a substance. It is referred to as the heat required to change one mole of liquid at its boiling point, which is equal to the standard atmospheric pressure. It is shown as kJ/kg. If the material is in a liquid state, it changes its form from liquid to vapor. This process of energy absorption is called heat vaporization. (See Why Ice floats on Water?)

4. Does Land Heat faster during the Day?

Yes, during the daytime the land gets heated up faster than the sea. This is because the land absorbs more solar radiation. Both the land’s surface and the vegetation it supports, retain more heat. As a result, the land gets heated up faster than water. (See What is 37.6 Celsius in Fahrenheit?)

5. What are Watts?

Watts are the SI units of power measured. Similarly, 1 kilowatt is equal to 1000 watts. Watts are the most regularly used unit of electrical power. Watts can be presented as 1 joule per second. Must see How to find Current Barometric Pressure near you?

6. Why does Liquid Water has the Highest Heat Capacity than Ice?

It is always observed that the basic difference between ice and water is that ice is a solid form of water and water is liquid. When the state of matter changes from solid to liquid or gas, it relies on the temperature, and the chemical compounds i.e., in this case, two hydrogen atoms equally secured to one oxygen atom.

  • It is often said that liquid water has the highest capacity to absorb heat because the liquid form of water can move. It has more space needed for heating and allows the overall temperature to increase.
  • But ice is different from the liquid. The ice surface area does not change because of its hard structure. The process starts when ice heats up and the energy must go somewhere. It begins to break into the solid structure and melts the ice into water. 

7. What are the Three Ways by which Heat can be Transferred?

Heat can be transferred in three ways and this can be useful to get a better idea of how to find the greatest amount of heat when warming 100 grams of ice:

  • Conduction – Heat is transferred from a high temperature to a low temperature through a medium or by directly touching the two mediums. Conduction occurs in solid, liquid, and gas, but mostly in solids.
  • Convection – Heat is transferred from a high temperature to a low temperature, without coming into direct contact with the medium.
  • Radiation – When heat is transferred from a high temperature to a low temperature, such as the sun, those waves or energy are known as radiation. 

8. What is the Difference between Heat and Temperature?

Heat is the form of energy that transfers from the hot body to the cold body. The SI unit of heat is Joule. Heat is measured using a calorimeter. Heat is written as Q.

The temperature is the measurement of both the hot and cold of the body. The SI unit of temperature is Kelvin. The measurement of temperature is done by the thermometer. Temperature is written in Celsius and Fahrenheit. Also, check out How can You measure Temperature?

9. Which has a Low capacity of Heat?

Some metals, like iron, have a very low heat capacity. The temperature of the iron can be quickly raised. Sand does have a low heat capacity. Water has a high specific heat capacity, as discussed earlier. This is why the land gets heated faster than the water. These differences could affect the water and land and even affect climate change. (See How Can You Measure Air Pressure?)

10. What is Water: a Universal Solvent?

Water is regarded as the universal solvent because it can dissolve any substance as compared to any liquid. This has become an important aspect for any living being on earth. Water can flow through the air, ground, or other bodies of water. The chemical composition and quality of the water make it an excellent solvent. Water has oxygen and hydrogen atoms, which help the molecules dissolve. Must see Which Best Describes the Dissolving Process?

So, the gist of the article is that some heat is required to break the hydrogen bonds between the molecules, raising the temperature of the water. This also requires a lot more work than melting ice. The joule is the unit of heat, which is a type of energy that moves from one body to another. The change of liquid and solid states was the subject of this article. Now you know the greatest amount of heat when warming 100 grams of ice and whether is the temperature a measure of the amount of heat stored in a substance. Also, the greatest value for liquid water is understood. (Also read How many Oxygen Atoms are in SiO2?)
