373 K

Question 12

what type of heat (convection,, conduction, or radiation) is a microwave?

Answer 12

radiation

Question 13

what is the equation for energy (with specific heat?)

Answer 13

E = m . Cp . (change in T)

Question 14

what is the equation for change in temperature

Answer 14

E / m . Cp

Question 15

what is the specific heat of water?

Answer 15

4,184

Question 16

if you’re conducting something, do you want to use a metal with a low specific heat or high specific heat?

Answer 16

LOW SH
because it takes less energy to heat up and will get hotter faster

Question 17

if you’re trying to cool an object down, (pull as much energy out of it as you can) should you use an object with high specific heat or low SH to draw the energy away?

Answer 17

HIGH SPECIFIC HEAT
because it can pull out and retain the most thermal energy and will TAKE a lot of energy to reach to equilibrium, cooling the other object down a lot

Question 18

if you’re heating up an object and dropping it into water with the goal to raise the temp of the water, should you drop in an object with high SH or low SH?

Answer 18

HIGH SPECIFIC HEAT
because it retains the most energy, so when heated it would release the most thermal energy

Question 19

explain specific heat

Answer 19

the amount of energy that it takes to raise or lower the temperature of an object. it gives away how fast the object will heat/cool and how it retains heat

Question 20

define heat

Answer 20

thermal energy that is capable of moving

Question 21

what is a vaccum

Answer 21

a place where no atoms/molecules are present, so no heat can transfer!

Question 22

when does a sea breeze happen?

Answer 22

WHEN THE SUN IS UP
hot air over sand rises, cooler air from the sea rushes in

Question 23

when does a land breeze happen?

Answer 23

WHEN SUN HAS SET
sand cools faster, air gets colder, rushes out to sea to fill in space from the rising warmer ocean air

Question 24

what is matter that contains a combination of different elements and compounds

Answer 24

mixture!

Question 25

what is the force between atoms and molecules that resists particle motion

Answer 25

intermolecular forces

Question 26

blood is a

Answer 26

homogeneous mixture

Question 27

salt water is a

Answer 27

homogeneous mixture

Question 28

S + NaCl + H20 is a

Answer 28

heterogeneous mixture
(sulfur plus salt plus water)

Question 29

the amount of heat needed to raise the temp of 1g of water by 1 C

Answer 29

calorie

Question 30

the amount of energy required to increase one pound of water by 1 degree F

Answer 30

BTU
