A certain amount of heat Q will warm 1 {\g} of material {\X} by 3^{\circ} {\C} and 1 {\g} of material Y by 4{ }^{\circ} {\C}. Which material has a higher specific heat capacity?

ICSE Class 10 Physics 2013 Solved Paper - Question 55

Question : 55 of 70

Marks: +1, -0

A certain amount of heat

Q

will warm

1 {\g}

of material

{\X}

3^{∘} {\C}

and

1 {\g}

of material

Y

4{ }^{∘} {\C}

. Which material has a higher specific heat capacity?

Solution:

\;\text " Specific heat capacity "\;=\;{ {\Q}}/{m ⋅ ∆ {\T}}

∵

Specific heat capacity

∝ \;{1}/{∆ {\T}}

So material

{\X}

has a higher specific heat capacity.
