On a winter day, the outside temperature is 0^(@)C and relative humidity 40%.The air from outside comes into a room and is heated to 20^(@)C. What is the relative humidity in the room? The saturated vapour pressure at 0^(@)C is 4.6mm of mercury and at 20^(@)C it is 18mm of mercury.

Thermodynamics- Heat And Temperature(उष्मागतिकी - ऊष्मा और तापमान)|OMR|Summary

Graphite is a much better conductor of heat and electricity than diamond. This is due to the fact that each carbon atom in graphite:( ग्रेफ़ाइट ऊष्मा ओर धारा का चालक होता है , क्यों ?)
