That statement is almost always false. When anything is heated, it expands ... with one tiny exception.
When water is heated from 0°C to 4°C, it contracts. I'm pretty sure that this is the only place in nature where this exception to the rule occurs. If it didn't, then life on Earth wouldn't be possible !
Answer: humans, oxygen, food. Or if you taking about space, there are planets, stars, and galaxys.

Answer:
Stunt Car A experiences a large force over a short period of time. Stunt Car B experiences a small force over a long period of time. Because of the force experienced by Stunt Car A, it will sustain more damage than Stunt Car B.
Explanation:
Both cars have the same mass and velocity, therefore they have the same momentum. During the collision, the total momentum of the car A and brick wall is conserved as well as the total momentum of the car B and the pile of leaves.
However, if we are to investigate the damage on each car, we should look at the cars not the whole system. So, the momentum difference between the cars gives us the impulse that the car felt.

Since the Car A will crash the wall quicker than the other car crashes through the pile of leaves,

which gives us
