21
Q
the standard deviation for a group of measurements is related to the blank of those measurements
A
precision
22
Q
rows on the periodic table are
A
periods
23
Q
one mm is defined as
A
1 cm^3
24
Q
molarity is defined as
A
moles of solute dissolved in 1 L of solution
25
when temp rises it’s
exothermic
26
if q is negative
so is change in H
27
when a system does work on the surroundings
the internal energy will decrease
28
what is proportional to avg kinetic energy
kelvin temp
29
if you increase the temp of a gas with a fixed volume what will pressure do
increase
30
what is an assumption in the kinetic molecular theory of an ideal gas
all collisions between molecules are elastic
31
because real gases have attraction for one another
real gases act more ideally at higher temps and lower pressures
32
how to convert celsius to kelvin
c+273.15
