# An apple loses 4.5 kJ of heat as at cools per degree Celsius drop in its temperature. What is the amount of heat lost from the apple per degree Fahrenheit in its temperature?

\(Q/^{\circ}C=4.5\;kJ

\\Q/^{\circ}F=\frac{Q/^{\circ}C}{1.8}

\\=\frac{4.5}{1.8}

\\=2.5\;kJ\)

Therefore amount of heat lost is 2.5 kJ.
