Answer 2

A liquid is kept in a china dish. The evaporation can be accelerated:-

• (d) All the above options are correct (By keeping the dish open, By blowing the air into the liquid and By keeping the dish under a running fan.
• Evaporation occurs when a liquid is transformed into a gas
• The rate of evaporation increases by increasing the surface area (putting water in an open China dish), and blowing of wind (blowing the air and keeping it under a running fan).

Melting point of ice is Zero Degrees Celsius.

• (a) Zero Degrees Celsius is the correct option.
• The melting point is the temperature at which a solid turns into a liquid.
• The melting point of water is the temperature at which ice turns into a liquid form of water which is 0°C.

Hence,

Q1 answer is (d) All the above options

Q2 answer is (a) Zero Degrees Celsius
