A metal ball of specific gravity 4.5 and specific heat 0.1cal/gm−∘C is placed on a large slab of ice at 0∘C. Half of the ball sinks in the ice. The initial temperature of the ball is:- (Latent heat capacity of ice =80cal/g, specific gravity of ice =0.9)

A cube of coefficient of linear expansion α is floating in a bath containing a liquid of coefficient of volume expansion γl. When the temperature is raised by ΔT, the depth upto which the cube is submerged in the liquid remains the same. Find relation between α and γl

In the following equation calculate the value of H.

1kg syeam at 200∘C=H+1kg water at 100∘C(Ssystem= Constant=0.5cal/gm∘C)

The amount of heat required to change the state of 1 kg of substance at constant temperature is called

The capacitance of the capacitors of plate areas A1 and A2(A1<A2) at a distance d is

The temperature on Celsius scale is 25∘C . What is the corresponding temperature on the Fahrenheit scale

Assertion. The size of a degree on Fahrenheit scale is smaller than that on celsius scale. Reason. When temperature on celsius scale reads 0^(@) , it reads 32^(@) on Fahrenheit scale.
