Equal masses of copper and rubber are raised to the same temperature. After sometimes, the copper was observed to be at a lower temperature because
the specific heat capacity of copper is lower than that of rubber
copper expands more than rubber
the specific heat capacity of rubber is lower than that of copper
rubber expands more than copper

As known that good conductors of heat have low specific heat capacity _ SHC is a measure of how well a body conducts a large amount of heat.
It is also important to know that as more heat is applied to a particular object, the temperature increases and vice versa.
So therefore a good conductor of heat whose temperature rises faster when more heat is applied (having a low SHC) wil also cool faster when the amount of heat is reduced.
However being a good conductor either the heat increase or decrease, the SHC remains the same.
The correct answer is C. the specific heat capacity of rubber is lower than that of copper.
Specific heat capacity is the amount of heat energy required to raise the temperature of a unit mass of a substance by one degree Celsius or one Kelvin. Since the masses of copper and rubber are equal and they are raised to the same temperature, the one with the lower specific heat capacity will reach a higher temperature first.
P.s: In my own opinion sha.
Ans is = specific heat capacity of copper is lower than that of rubber
copper expands
The correct answer is "the specific heat capacity of copper is lower than that of rubber."
When two objects with the same mass are heated to the same temperature, they will absorb the same amount of heat energy. The specific heat capacity of a material is the amount of heat energy required to raise the temperature of one kilogram of that material by one degree Celsius.
Copper has a lower specific heat capacity than rubber, which means that it requires less heat energy to raise its temperature by one degree Celsius. As a result, when the same amount of heat energy is transferred to both copper and rubber, the temperature of copper will increase more quickly than that of rubber.
Therefore, when both copper and rubber are raised to the same temperature and left for some time, the copper will cool down faster than the rubber, and its temperature will become lower
The correct answer is:
C. the specific heat capacity of rubber is lower than that of copper.
Explanation:
Specific Heat Capacity: This is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius. Copper has a higher specific heat capacity compared to rubber, meaning it requires more heat to increase its temperature.
When equal masses of both materials are raised to the same temperature, rubber, having a lower specific heat capacity, will lose heat more quickly than copper when they are allowed to cool.
Therefore, after some time, the copper maintains a higher temperature because it retains heat more effectively than rubber.
Myschool should compare this question to question 4, (1982).
they are two contrasting answers and I think option C is correct
The answer is A. Object with higher specific heat capacity have lower change in temperature
The answer is C a body that is het up easily has a low specific heat capacity because a small amount of heat will be required to raise it's temperature 1°k.
