Answer:
Explanation:
lower the temperature -the higher the temp the more energy the molecules absorb. The more energy they have the more they move
The most likely answer to this problem would be (1) more mass and more inertia.
A 15-kilogram cart at rest and a 5-kilogram box would make up a 20-kilogram cart and box that is at rest on a horizontal surface. The mass changed into something more, of course, as a result of combining the two object into one and by combining the two objects' mass, the inertia that it previously possessed as a cart by itself was increased when the inertia of the box was also combined to the cart.
heat = mass x spec heat x temp rise
40.5=15.4x10^-3xspec heatx11.2
