Volume & Temperature: Charles's Law

Video for Charles's Law

Notes for Charles's Law

V=bT

or

V₁ = V₂

T₁ T₂

Note:

Volume is directly proportional to Temperature

• • When temperature goes up, volume goes up

  • When temperature goes down, volume goes down

  • Temperature MUST BE EXPRESSED IN KELVIN!!!

T_k= T_c + 273

Exercises for Charles's Law

For each of the following sets of volume/temperature data, calculate the missing quantity. Assume that the pressure and the amount of gas remain constant.

1. V= 100. mL at 74 C ; V=? at -74 C

2. V= 500. mL at 100 C; V=600. mL at ? C

3. V= 10,000 L at 25 C ; V = ? at 0 K

4. V= 22.4 L at 0 C; V=44.4 L at ? K

5. V= 1.0 x 10-3 mL at -272 C ; V= ? at 25 C

6. V= 32.3 L at -40 C; V= 1000. L at ? C
