Calculate specific heat of liquid if a 450. g iron block is heated to 98.0 c and then droped into a calorimeter with 125 g of unknown liqid at 19.8 c. after 2 minutes the temp inside the calorimeter rise to a maximum of 40.4 c.

Specific heat of liquid

Explanation:

We know in thermal equilibrium :

Loss in heat by iron block = Gain in heat by liquid .

Specific heat of iron = 0.45  { source internet }

Now , loss in heat by iron block =

Heat gain by liquid=

Equating both we get :

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!
