1. The density of a material Ais 1500 kg/m and that ofanother mateial B is 2000 kg/m It is found that theheat capacity of 8 volumes of A is equal to heatcapacity of 12 volumes of B. The ratio of specificheats of A and B will be(A) 1:2 (B)3:1 3:2 (D) 2:1

Answer»

The density of material A= 1500 kg/m^3

Density of material B = 2000 kg/m^3.

According to the findings,

Heat capacity of 8 volumes of A = heat capacity of 12 volumes of B

Ratio of specific heat= SA/ SB=?

The ratio of specific heat can be calculated by following formula:

Sa/ma x mb/Sb

=2:1
