The correct answer is c) gas.
In gases, in fact, particles are not bound together (and the intermolecular forces between them are negligible) and they are completely free to move. For this reason, when a gas is put in a container, the particles of the gas will move in every possible direction, filling all the space available in the container (for this reason, we also say that gases have no fixed shape).

Answer:
(c) a baseball that is caught and then thrown back
Explanation:
The case when the baseball is caught and thrown back undergoes the maximum change in the momentum of the ball. The ball in this case reverts its direction of velocity therefore the velocity becomes opposite of what it was earlier and being a vector quantity it has a change in sign and hence the difference between the final and the initial values is largest than the cases in which one of the velocity is zero.
Answer:
specific heat
Explanation:
Specific heat is the amount of heat required to change the temperature of 1 gram of a substance by 1°C, and it is related to the chemical composition of the substance
