CH6 Molecules and Matter Flashcards
What are the units for pressure
Pascals
What is the formula for pressure in a liquid?
pressure = density x gravity x height
what is the formula for pressure in a solid
pressure = force/ area
What apparatus would you require to find the density of an irregular object
A eureka can and a measuring cylinder
What does the pressure in a liquid depend
depth
What is absolute zero
The point where the internal energy of a substance is at a minimum
What scale of temperature do gas laws use
Kelvin scale
how dow pressure in a liquid change with depth
it increases
when do objects float in water
when they are less dense than water
how do you convert celsius to kelvin
add 273 to the value
what assumption do you make for Boyles laws
Mass of gas/number of particles remains constant
what is the density of water
1000kg/m^3
What are the properties of a solid
fixed arrangement, vibrate about a spot, tightly bound and cannot be compressed
what are the properties of a liquid
loosely bound, can be poured, take shape of container and not easily compressed
properties of a gas
free to move, fills container, can be poured, easily compressed
