going from a gas directly to solid is known as
deposition
200
what is this?
Daltons law of partial pressure

What is the difference between work and heat?
Heat: Transfer of energy in a disorderly format, into or out of a system
Work: Transfer of energy in an orderly format.

What is called when heat is added to a substance but the temperature of the substance does not increase?
phase change
300
has no fixed shape and no fixed volume
gas

a gas that conforms, in physical behaviour, to a particular idealized relation between pressure, volume, and temperature
ideal gas

The specific heat of nickel is 540 J/kgK. If you add 5400 J of heat to 1.0 kg of nickel, by how many Kelvins will the temperature rise?
10 KELVIN
300
When will q have a positive value and when negative?
q pos = endothermic
q neg=exothermic

Oil does not dissolve in water because?
water is polar
400
plasma
Plasma is a form of matter in which many of the electrons wander around freely among the nuclei of the atoms.
400
what is the symbol for temperature?
T
400
why is a burn from steam at 100 celcius is expected to be more severe than a burn from boiling water at 100 celcius?
It becomes water again. This is a fundamental change from a gas to a liquid. Steam touches your skin, drops in temperature — transferring that energy (and heat) to your skin — and switches back into liquid form.
400
Why is water's specific heat (H2O) stronger than methane's CH4?
water has hydrogen bonds (strong) while methane can only form dispersion forces (weak)
400
What mixture will not be separated by dialysis?
solutions
500
any substance at a temperature and pressure above its critical point, where distinct liquid and gas phases do not exist, but below the pressure required to compress it into a solid.
supercritical fluid

You have a 4 L balloony in your freezer at -12C and the air pressure is 1 atm. you then decide to take balloony scuba diving with you in the tropics and the pressure is 5 atm and balloony shrinks to 1.08 L, what is the temperature of the water in the tropics?
oop
