Specific heat is heat per unit mass per unit temperature change. s = m Δ T Q A change of 1 ∘ F is smaller than a change of 1 ∘ C. Δ T F = 5 9 Δ T C The temperature interval is numerically larger, so specific heat decreases.

If, in defining the specific heat, temperature is represented in $^{\circ}$ F instead of $^{\circ}$ C then the value of specific heat will

Options:

Answer:

Solution:

Specific heat is heat per unit mass per unit temperature change.
$s = \frac{Q}{m Δ T}$
A change of $1^{\circ}$ F is smaller than a change of $1^{\circ}$ C.
$Δ T_{F} = \frac{9}{5} Δ T_{C}$
The temperature interval is numerically larger, so specific heat decreases.
