Question

Which of the following concerning specific hear is correct?

a. Specific heat can be measured only when the substance is in a solid state.
b.Under similar circumstances, substances with low specific heat increase in temp more when heated than do substances with high specific heat.
c. A correct set of units of specific heat is cal/*C
d.More than one correct response
e. No correct responses

Answer 1

The correct options are 'Under similar circumstances, substances with low specific heat increase in temp more when heated than do substances with high specific heat' and 'A correct set of units of specific heat is cal/g°C'.

Step-by-step explanation:

The correct answer concerning specific heat is: Under similar circumstances, substances with low specific heat increase in temperature more when heated than do substances with high specific heat. This is because specific heat is a measure of how much energy is needed to raise the temperature of 1 gram of a substance by 1°C. Specific heat can be measured in various states of matter (solid, liquid, or gas), not just in a solid state, making option a incorrect. A correct set of units for specific heat is indeed cal/g°C (or cal/g K), as mentioned in the question, which makes option c correct as well. Therefore, the correct responses are b and c.
