A geyser heats water flowing at the rate of 3.0 litres per minute from `27 °C` to `77 °C`. If the geyser operates on a gas burner, what is the rate of consumption of the fuel if its heat of combustion is `4.0 × 10^4 J//g` ?

A geyser heats water flowing at the rate of 3.0 litres per minute from 27^(@)C to 77^(@)C . If the geyser operates on a gas burner, what is the rate of consumption of the fuel if its heat of combination is 4.0 xx 10^(4) J cdot g^(-1) ?

What is the thermal capacity of 40 gm of aluminium? Specific heat of aluminium is 0.2 cal g^-1^@C^-1 .

A vacuum flask contains 0.4 kg liquid paraffin whose temperature can be increased at the rate of 1^(@)C per minute using an immersion heater of power 12.3 W. When a heater of 19.2 W is used to heat 0.5 kg of liquid paraffin, in the same flask, the rate of rise temperature is 1.2^(@)C per minute. What is specific heat of the paraffin?

The heat liberated when 1.89 g of benzoic acid is burnt in a bomb calorimeter at 25^@C increase the temperature of 18.94 kg of water by 0.632^@C . If the specific heat of water at 25^@C is 0.998 cal/g-deg, the value of the heat of combustion of benzoic acid is

A vacuum flask contain 0.3 kg of liquid paraffin whose temperature can be increased at the rate of 1^(@)C per minute using an immersion heater of power 12.3W. When a 19.2 W heater is used to heat 0.4 kg of liquid paraffin, in same flask, the rate of rise of temperature is 1.2^(@)C per minute. Find the specific heat of paraffin and the thermal capacity of the flask.
