Question

Answer this question of Physics 11th

Answer 1

Mass of copper block= 2.5 kg
Temperature of furnace =500 C
Final temperature of block =0 C
Total heat released from block =ms∆t
=2.5*390*500 =487500
=M* 335000
Therefore M =1.45kg

Answer 2

Hey!!

Here is your answer -

Mass of copper block = 2.5 kg

Temperature of furnace = 500 C

Final temperature of block = 0 C

Total heat released from block = ms∆t

= 2.5 x 390 x 500 = 487500

= M x 335000

Therefore M =1.45kg
