Question

If the temperature of a gas increased from 100 K to 200 K and the volume of a gas decreased from 20 L to 10 L, what is the new pressure if the original pressure was 100 kPa?
Group of answer choices

A. 100 kPa

B. 400 kPa

C. 200 kPa

D. 50 kPa

Answer 1

Answer:

B. 400 kPa

Explanation:

the pressure increases, when the temperature increases. and it increases, when the volume decreases.

both cases happen here, each with the factor 2.

so, the pressure increases by the factor 2×2 = 4.

4×100 = 400 kPa
