When two heating devices are used to heat two different substance A and B the heat absorbed by A after 2 seconds is found to be equal to the heat absorbed byy B after 3 seconds. The rise in temperature of A after 5 seconds is found to be equal to the rise in temperature of B after 6 seconds.i the ratio of masses o A and B is 1:2, determine the ratio of the specific heat capacities of two substances.

Text Solution

Verified by Experts

Equate the heat absorbed by A in 2s to that of B in 3s. Find the ratio of heat supplied to A and B in unit time.
find the ratio of heat supplied in 5s to A to heat supplied to B in 6s to determine the ratio of specific heat.
