Q. 4 D4.1( 8 Votes )

Solve the followi

Answer :

Given data:


● Specific heat of substance A = c


● Specific heat of substance B = 2c


● Heat was given to substance A = Q


● Heat was given to substance A = 4Q


● Mass of A = m


Calculation:


The formula to calculate the heat energy given to body A is as follows.


Q = m×c×∆T …………. (1)


The formula to calculate the heat energy given to body B is as follows.


4Q = mB×2c×∆T ……………. (2)


Divide equation (2) by equation (1).



or



or


mB = 2m


The mass of substance B is 2m.
