Which of the following is/are not true about the heat capacity of a substance?
(i) It is an intensive property
(ii) Its S.I unit is \(jK-1\)
(iii) It is an extensive property
(iv) Its S.I unit is \(jkg-1\)
(i) It is an intensive property
(ii) Its S.I unit is \(jK-1\)
(iii) It is an extensive property
(iv) Its S.I unit is \(jkg-1\)
(i) and (iii) only
(i), (ii) and (iv) only
(i) and (iv) only
(ii) and (iii) only
Vysvětlení
The S.I unit of heat capacity is JK-1 and it is an extensive property as it depends on the amount of substance present.
Therefore, (i) and (iv) only are not true
Therefore, (i) and (iv) only are not true
