Question

which statement defines specific heat capacity for a given sample?
○ the temperature of a given sample
○ the temperature that a given sample can withstand
○ the quantity of heat that is required to raise the sample’s temperature by 1°c (kelvin)
○ the quantity of heat that is required to raise 1 g of the sample by 1°c (kelvin) at a constant pressure

Explanation:

To determine the correct definition of specific heat capacity, we analyze each option:

• The first option refers to temperature, not heat capacity, so it's incorrect.
• The second option is about temperature tolerance, not heat capacity, so it's incorrect.
• The third option describes heat capacity (not specific, as it doesn't specify mass), so it's incorrect.
• The fourth option correctly defines specific heat capacity: it's the heat required to raise 1 gram of a substance by \(1^\circ\text{C}\) (or 1 Kelvin) at constant pressure.

Answer:

D. the quantity of heat that is required to raise 1 g of the sample by \(1^\circ\text{C}\) (Kelvin) at a constant pressure
