### Re: Thermodynamics B/C

2.50 L of gas originally at 60 ̊C is warmed to 145 ̊C.

1. What is the new volume if the pressure remains constant?
2. Who named this law?
1) 1.99 L
2) Jacques Charles if you mean who the law was named after
Shouldnt the gas expand?
It should expand. I get 3.14L but there is technically only one significant figure because of 60C. So it would be 3L

### Re: Thermodynamics B/C

Just going to ask the next question..

5 moles of a monatomic ideal gas isobarically and adiabatically contract by 1.5 L, changing from 100 degrees Celsius to 80 degrees Celsius. Find the final volume and pressure of the gas.

Sorry, you're right, it should be contract, not expand
Edited the original post to clarify.

What is the heat energy required to completely vaporize 110g of water beginning at 0°C? (The heat capacity of water is 4.2 J/g⋅K and the ΔH
vaporization of water is 2260 kJ/kg

$100 K * 4.2 \frac{J}{g*K} * 110 g + 2260 J/g * 110 g$

### Re: Thermodynamics B/C

All right! When heat flows through a wall, what kind of process is that?

a flow process?
