The heat of vaporization of carbon tetrachloride (CCl4) is 197.8 J/g. How much energy is absorbed by 1.35 mol CCl4 when it vapor
const2013 [10]

Energy absorbed from changing the phase of a substance from the liquid phase to gas phase can be calculated by using the specific latent heat of vaporization. Calculation are as follows:

 

<span> Energy = 1.35 mol  CCl4 ( 153.81 g / 1 mol ) x 197.8 J/g </span>

 

<span>Energy = 41071.88 J</span>

What is the energy change per gram of ice when an iceberg composed of pure water, cp = 2.06 J/(g·K), is heated from 25°C to 15°C
Gemiola [76]

Answer:

A. 21 J

Explanation:

Your temperature change is 10 degrees Celsius, or 10 Kelvin, it makes no difference either way.

Cp = 2.06 J/g•K

Multiply by the temperature change to just get J/g

2.06 J/g•K • 10 K = 20.6 J/g ≈ 21 J/g
