366346 An experiment takes 10 minutes to raise the temperature of water in a container from \(0^\circ C\) to \(100^\circ C\) and another 55 minutes to convert it totally into steam by a heater supplying heat at a uniform rate. Neglecting the specific heat of the container and taking specific heat of water to be \(1\,cal\,g - \,^\circ C\), the heat of vapourisation according to this experiment will come out to be

366347 Assertion :
Cooking food is difficult on hills.
Reason :
The boiling point decrease with increase in pressure.

366348 The latent heat of vaporisation of water is more than latent heat of fusion of ice ?

366349 A copper block of mass \(2.5\;kg\) is heated in furnance to a temperature of \(500^\circ C\) and then placed on a large ice that can melt? (Specific heat of copper \( = 0.39\;J/g - K\); heat of fusion of water \( = 335\;J/g)\)
