11/17 quiz

Question 1

absolute zero

Answer 1

0 kelvin or 0K

Question 2

why can’t temperatures be below 0 kelvin?

Answer 2

because kelvin measures kinetic energy and 0 kelvin means 0 kinetic energy, therefore at 0 kelvin, there is no motion.

Question 3

specific heat-

Answer 3

different substances will heat at different rates

Question 4

formula for calculating the heat of a substance:

Answer 4

q= m•c•(change)T

Question 5

q=

Answer 5

heat/ energy (J)

Question 6

m=

Answer 6

mass (g)

Question 7

c=

Answer 7

specific heat (J/g•(degrees)C)

Question 8

T=

Answer 8

temperature (degrees C)

Question 9

J/g•(degrees)C= (means)

Answer 9

for every 1 joule of heat added, the temperature of 1 gram of a substance will change by 1

Question 10

heating curve-

Answer 10

a graph that shows the phases of matter and phase changes as they relate to thermal energy and temperature

Question 11

how much heat and weight does ICE have to have to heat up to water?

Answer 11

C= 2.1 J/g•(degrees)C

Question 12

how much heat and weight does WATER have to have to heat up to steam?

Answer 12

C= 4.18 J/g•(degrees)C

Question 13

how much heat and weight does STEAM have to have to heat up?

Answer 13

C= 1.7 J/g•(degrees)C

Question 14

what are the phases of the heating curve?

Answer 14

ICE- melts to water or crystallizes
WATER- vaporizes to steam or condensates back to ice
STEAM

Question 15

KMT (kinetic molecular theory)-

Answer 15

relates motion of particles to the energy
