Explain why a beaker filled with water at `4^@ C` overflows if the temperature is decreased or increased.

Explain why water wets glass.

For every 10^@C rise in temperature the rate of reaction increases nearly

Rate of reaction decreases as temperature increases.is it true or false

Explain why normality and molarity vary with temperature while molality is: temperature independent.

Explain, why ethanol is miscible in water in all proportion.

The temperature co-efficient of a reaction is 2. How many times the rate of reaction will increase if the temperature is increased by 50^@ C?

A ballon partially filled with hydrogen at normal pressure and temperature is released from the ground . At 20 kilometer up in the atmosphere the temperature is - 40^@C and the pressure is 10 cm of mercury . Calculate the percentage increase in volume of the gas in the balloon.

The rate of a reaction is doubled for every 10^@C rise in temperature. The increase in rate as a result of increase in temperature from 10^@C to 100^@C is:
