Answer: A. Copper
Explanation:
The amount of heat needed to increase the temperature of a given mass of a substance by one degree Celsius is known as specific heat. To raise a substance's temperature by one degree Celsius, the material with the highest specific heat will need to be heated up the most.
----------------------------------------------------------------------------------------------------------
Copper has a specific heat of 0.385 J/g°C. Therefore, 0.385 joules of energy are required to raise the temperature of 1 gramme of copper by 1 degree Celsius. As a result, compared to the other possibilities, copper will take the greatest heat to raise its temperature. Because of this, copper has the highest specific heat among the available metals.
----------------------------------------------------------------------------------------------------------
Gold has a specific heat of 0.129 J/g°C. This is less than copper, for example. This means that compared to copper, gold will require less heat to raise its temperature. Gold is not the ideal choice for the substance with the highest specific heat, for this reason.
----------------------------------------------------------------------------------------------------------
Iron has a specific heat of 0.449 J/g°C. The specific heat of copper is lower even though this is higher than that of gold. This shows that compared to copper, iron will require less heat to raise its temperature. Iron is not the ideal choice for the substance with the highest specific heat, for this reason.
----------------------------------------------------------------------------------------------------------
Aluminium has a specific heat of 0.902 J/g°C. Despite being higher than that of iron, this still falls short of copper's specific heat. This implies that compared to copper, aluminium will take less heat to raise its temperature. Aluminium is not the ideal material for the substance with the highest specific heat, for this reason.
----------------------------------------------------------------------------------------------------------
Copper, which has a specific heat of 0.385 J/g°C, has the highest specific heat among the materials listed since it is higher than the specific heats of gold, iron, and aluminium.
