Assertion : If the temperature of a star is doubled then the rate of loss of heat from it becomes 16 times.
Reason : Specific heat varies with temperature.
The correct answer is option B. Both the assertion and reason are true, but the reason is not the correct explanation of the assertion.
Explanation:
Assertion: If the temperature of a star is doubled, then the rate of loss of heat from it becomes 16 times.
Reason: Specific heat varies with temperature.
Explanation:
The rate of heat loss from a star is determined by various factors, including the temperature and the specific heat capacity of the material of the star. However, the specific heat capacity alone does not determine the rate of heat loss.
Specific heat capacity is the amount of heat required to raise the temperature of a unit mass of a substance by a certain amount. It is a property of the material and is typically measured in units of J/(kg·K).
When the temperature of a star is doubled, the rate of heat loss from the star does not necessarily become 16 times. The rate of heat loss depends on various factors such as the surface area, emissivity, and temperature difference between the star and its surroundings.
The specific heat capacity of a substance only affects the amount of heat required to raise its temperature, but it does not directly determine the rate at which heat is lost. Therefore, the reason given in the assertion is not the correct explanation for the relationship between the temperature of a star and its rate of heat loss.
Hence, the correct answer is option B. Both the assertion and reason are true, but the reason is not the correct explanation of the assertion.
Reason : Specific heat varies with temperature.
The correct answer is option B. Both the assertion and reason are true, but the reason is not the correct explanation of the assertion.
