Investigationg Heat theory

Question 1

what is the bodys normal temp

Answer 1

36-37 degrees cel

Question 2

What is heat?

Answer 2

Heat is the thermal energy that transfers when something is hot and cold that is in contact. (Measured in joules)

Question 3

What is temp?

Answer 3

Determines how quickly the particles are moving (measured in cel)

Question 4

How does temp affect particles (name 3)

Answer 4

1. ALL MATTER IS MADE UP OF PARTICLES
2. Always in a contanst state of motion
3. The more energy the particles have the more faster they travel

Question 5

What is the heat capacity formula

Answer 5

Q=mc angle T

Question 6

what is conduction

Answer 6

When particles gain energy from the hot substance. (Through solids) (contact)

Question 7

example of conduction

Answer 7

a metal rod

Question 8

what is convection

Answer 8

When particles gain energy from the source (doesnt need to have any contact)

Question 9

example for convection

Answer 9

beaker getting hot by a bunsen burner

Question 10

what is radaition

Answer 10

when you adsorb heat

Question 11

example of radiation

Answer 11

heater

Question 12

Infra-red radiation??

Answer 12

When you cant see the radiation but its there through shinyness??

Question 13

Which color adorbs more heat

Answer 13

Dark colors

Question 14

why does dark colors adsorb more heat

Answer 14

because the heat bounces off lighter coloured objects

Question 15

what are some examples of heat in every day life

Answer 15

walking on fire or thermos

Question 16

why is metal a good conductor

Answer 16

because the atoms form a matrix which means the atoms can move better
