Mary wants to remove a dent from a ping-pong ball without cutting into the sealed ball. she decides to put the ball in a bowl of boiling water. after a while, mary observes the dent disappearing until it is no longer present. why did the dent disappear?

Athe water caused an increase in temperature of the air inside the ball and a decrease in pressure.
Bthe water caused an increase in temperature of the air inside the ball and an increase in pressure.
Cthe water caused a decrease in temperature of the air inside the ball and a decrease in pressure.
Dthe water caused a decrease in temperature of the air inside the ball and an increase in pressure.

The dent (hollow area formed by pressing or hitting) from the ping-pong ball disappeared because energy was transferred from the hot boiling water in which the ball was placed to the air inside the ball. This transferred energy will increase the temperature of the air inside the ball and the air molecules will begin to move faster with a greater force. Hence, causing an increase in pressure.

Answer:

The right option is; b. the water caused an increase in temperature of the air inside the ball and an increase in pressure.

The dent (hollow area formed by pressing or hitting) from the ping-pong ball disappeared because energy was transferred from the hot boiling water in which the ball was placed to the air inside the ball. This transferred energy will increase the temperature of the air inside the ball and the air molecules will begin to move faster with a greater force. Hence, causing an increase in pressure.
