[Ques. 4] The latent heat of vaporization of water is roughly 10 times the latent heat of fusion of water. The amount of heat required to boil away 1 kg of water is 10 times the amount of heat required to melt 1 kg of ice.

[Ques. 5] The specific heat capacity of water is about twice the specific heat capacity of ice. The amount of heat required to boil 1 kg of water is twice the amount of heat required to melt 1 kg of ice.
Indicate whether the statement is true or false
[Ques. 6] Water is good for putting out fires because it has a very high latent heat of vaporization.

[Ques. 7] When water boils, its temperature increases.
Indicate whether the statement is true or false
[Ques. 8] When you add heat to ice, its temperature always stays constant.
Indicate whether the statement is true or false
[Ques. 9] When ice melts, its temperature increases.
Indicate whether the statement is true or false
[Ques. 10] The specific heat capacity of copper is three times the specific heat capacity of lead. Equal masses of copper and lead are heated from room temperature to the temperature of boiling water. To achieve this, the amount of heat added to the copper is 3 times the amount of heat added to the lead.
