Question 254

Equal masses of two different liquids, X X\,X and YYY, are put into identical beakers.

Liquid X X\,X is heated for 240 s and liquid Y Y\,Y is heated for 80 s by heaters of the same power. Each liquid undergoes the same rise in temperature.

Which statement is correct?

A

Liquid YYY receives more thermal energy than liquid XXX.

B

The thermal capacity of liquid XXX is one-third of the thermal capacity of liquid YYY.

C

The specific heat capacity of liquid XXX is three times the specific heat capacity of liquid YYY.

D

Both liquids have the same specific heat capacity.
