Question 1 (2.5 points) Steam can burn a person badly because? Question 1 options: It requires a tremendous amount of energy to change steam to water C A tremendous amount of energy is released when steam condenses to water The temperature drop from steam to water is so great. Question 2 (2.5 points) The specific heat of water is 1.0 cal/g/°C and that of Ethanol is .75 cal/g/"C. If you mix 500g of Ethanol at 10 oC with 500g of Water at 90 °C the temperature of the mixture when it reaches equilibrium will be: (assume the liquid mixture is insulated from the surroundings so heat does not escape) Question 2 options: a) 50°C b) Greater than 50°C c) Less than 50 °C Question 3 (2.5 points) Energy is required to change the state of a material from a liquid to a gas. This energy mainly goes in to? Question 3 options: Changing the temperature of the material Breaking the molecular bonds o) Cusing the molecules to beome more re

Explanation / Answer

1.Steam have latent heat of energy which is released when stem condenses to water.

2. It will be greater than 50 as specific heat of water is higher so it will release equal energy for smaller temperature difference as compared to ethanol.

3. Breaking the molecular bonds
