How many kJ of heat are necessary to melt 32 grams of ice at -10 °C and boil it all away as water vapor?
Hint: Do this problem in steps! Four steps to be exact!
You will need the following information:
- Specific heat capacity of ice (this is the slope of the first part of the graph below): 2.1 kJ/kg per °C
- Latent heat of melting (fusion) of ice (this is the length of the first plateau on the graph): 335 kJ/kg (note there is no temperature change associate with latent heat).
- Specific heat capacity of water (this is the next slope on the graph): 4.2 kJ/kg per °C
- Latent heat of vaporization of water (the final plateau on the graph): 2260 kJ/kg (note this is a huge number and again, the temperature does not increase as the water vaporizes).

What is the measure of the actual amount of water vapor in the air called?
This is called the absolute humidity, usually expressed in grams of water vapor per kilogram of air, but also by water vapor per unit volume of air (e.g. grams per cubic meter).
How many joules of energy are necessary to heat a sample of water with a mass of 46.0 grams for 0.0?
46 calories (or 192, 464 joules) for each Celsius degree.
Is water vapor the most dense form of water?
i have read water has maximum density at temprature of 4 degree celsius...so water vapour is not most dense form of water.

Is At -10 degree c you have water vapor?
Water vapor can exist at this temperature if it is supercooled (if there is no condensation nuclei for it to form on).

yes it is necessary to subtract the water pressure
What is the measure of the actual amount of water vapor in the air called?
This is called the absolute humidity, usually expressed in grams of water vapor per kilogram of air, but also by water vapor per unit volume of air (e.g. grams per cubic meter).
What is the water that has been heated to a gas?
Water can be heated at 100 degree celsius to give steam which is the gaseous state of water
It is necessary for the condensation of water vapor?
yes or else it wouldn't rain
