To determine the temperature increase of an object, you need to consider factors such as its mass, velocity, and the material from which it is made. Let's evaluate the given options:
a. Its mass: The temperature increase of an object is not directly dependent on its mass. Mass affects the amount of heat required to raise the temperature of an object, but it does not determine the temperature increase itself.
b. Its velocity: The temperature increase of an object is also not directly influenced by its velocity. Velocity affects kinetic energy, but it does not impact the temperature increase of an object.
c. The material from which it is made: The material from which an object is made plays a crucial role in determining its temperature increase. Different materials have different thermal conductivities and heat capacities, which affect how efficiently heat is transferred into or out of the object.
d. Answers (a) and (c): While mass does not directly affect the temperature increase, the material does. Therefore, the correct choice is (d) "answers (a) and (c)" since it includes the correct consideration for the impact of the material from which the object is made.
e. None of the above: Since options (a) and (c) are both relevant to the temperature increase of an object, option (e) "none of the above" is incorrect in this case.
Regarding which would cool faster at the beach, the ocean water or the beach sand, we need to consider their respective properties. Ocean water has a higher specific heat capacity than sand, meaning it can absorb more heat energy before its temperature decreases. As a result, the beach sand is likely to cool faster than the ocean water when exposed to the same cooling conditions, such as wind or lower ambient temperatures.
