Chem thermo Flashcards
1
Q
calorimetry
A
measurement of heat change
2
Q
calorimeter
A
device that measure the amt/ of heat absorbed/released
ex. styrofoam cup
3
Q
coffee cup calorimeter
A
record temp change as chem react
4
Q
bomb calorimeter
A
food lit on fire
5
Q
temp change is dependent on
A
- amt. of heat added
- mass of substance
- composition of the substance
6
Q
specific heat (c)
A
amt. of heat needed to raise the temp of 1 gram of a substance by 1 celsius
7
Q
units of specific heat
A
cal/g’C
J/g’C
8
Q
specific heat of H2O
A
4.18 J/g’C
1 cal/g’C
9
Q
q=mct
A
q=heat (J or cal)
m=mass (g)
c= specific heat
t= change in temp (‘C), T final - T initial
