Question

The graph shows a sample of gas when it is hot, cold, and at room temperature.

Answer 1

Answer:

B represents gas at room temperature and C represents hot gas.

Explanation:

• As the temperature increases, the no. of particles that has higher energy increases.

So, A represents the cold gas, because it has the lowest no. of particles that has high energy.

B represents the gas at room T because it has more no. of particles with higher energy.

C represents the hot gas, because it is the curve that has the highest no. of particles with high energy.

• So, the right choice is:

B represents gas at room temperature and C represents hot gas.
