100.g of ice at 0C are added to 300.g of water at 25°C. Is it sufficient ice to lower the temperature of system to 0°C and still have ice remaining?
At 40 degrees celsius the vapor pressure of methyl alcohol is 254 mmHg and at the same temperature the vapor pressure of ethyl alcohol is 135 mmHg.
A gas originally at 27 degrees celsius and 1.00 atm pressure in a 3.9 L flask is cooled at constant pressure until the temperature is 11 degrees celsius. determine the new volume of the gas and express your answer in Litre.
