Final answer:
The correct relationship is that if the temperature increases, then q (heat absorbed) also increases. This is because the amount of heat absorbed is directly proportional to the temperature change, as represented by the equation q = mcΔT, with q being the heat exchanged, c the specific heat, m the mass, and ΔT the temperature change. Therefore correct option is A
Step-by-step explanation:
Regarding the relationship between heat absorbed (q) and temperature change (ΔT), the correct statement is: If the temperature increases, then q also increases. When a substance gains thermal energy, its temperature increases, meaning the final temperature is higher than the initial temperature (ΔT > 0), and hence q is positive. Conversely, if a substance loses thermal energy, its temperature decreases, signalling that the final temperature is lower than the initial temperature (ΔT < 0), and q is negative.
The amount of heat transferred to cause a temperature change in a substance depends on factors such as the substance's specific heat (c), mass (m), magnitude of the temperature change (ΔT), and phase of the substance. Therefore, for the same mass and specific heat of a substance, the amount of heat absorbed or released is directly proportional to the temperature change. This is summed up by the equation q = mcΔT, where q represents the heat exchanged, c is the specific heat, m is the mass, and ΔT is the temperature change.
Which of the following is correct in the case of the amount of heat absorbed and temperature?
A) If the temperature increases, then q also increases. B)If the temperature increases, then q decreases.
C) If the temperature decreases, then q is constant. D)If the temperature decreases, then q increases.
