Question

A gas with a volume of 535 mL at a temperature of -25C is heated to 175C. What is the new volume of the gas if pressure and number of moles are held constant?

Answer 1

Answer:

The new volume of the gas is 966 mL

Explanation:

Step 1: Data given

Volume = 535 mL

Initial temperature = -25.0 °C

Final temperature = 175 °C

Step 2: Calculate the new volume

V1/T1 = V2/T2

⇒with V1 = the initial volume = 535 mL = 0.535 L

⇒with T1 = -25 °C = 248 K

⇒with V2 = the new volume = TO BE DETERMINED

⇒with T2 = the new temperature = 175 °C = 448K

0.535 L/ 248 K = V2 / 448K

V2 = 0.966 L =966 mL

The new volume of the gas is 966 mL

Answer 2

Answer:966.45ml

Explanation:

Using Charles law.. V1/T1=V2/T2

V1=535ml

T1=-25+273

=248k

T2= 175+273=448k

V2=?

V2= V1*T2/T1

V2=535*448/248

V2=239680/248

V2=966.45ml
