PARTICLE THEORY part 1 ~ heat

Question 1

What are the four main points of the particle theory of matter?

Answer 1

All matter is made up of small particles known as atoms. Particles of matter are constantly in motion. Particles of matter attract each other. Particles of matter have spaces between them

Question 2

What’s a real-life example that demonstrates each component of the particle theory

Answer 2

1/particles are attracted/ when we heat up an aluminum can and then quickly cool it the atoms will attracted suddenly in hard due to all the energy escaping
2/particles are everything/ when you sit on a chair it doesn’t collapse because it’s made up of particles
3/ particles are constantly moving / when we cook food the smell moves around the house.
4/ particles have space in between them/ when we dissolve sugar in water it takes up the acces space in the water particles

Question 3

What are three states of matter

Answer 3

Liquid-juice
solid-bed
gas-hydrogen gas

Question 4

How are solids, liquids and gases similar? how are they different?

Answer 4

= They are all made of particles/atoms. they have volumes and their particles move.
= They all move at different speed. they have different amount of space between their atoms. their energy levels are different

Question 5

Use the particle theory to explain why gases expand more than liquids or solids when they are heated.

Answer 5

Particles are constantly moving and their are space between particles and the heat creates kinetic energy which makes the atoms move faster and they expand because they are poorly attracted.

Question 6

how are temperature and heat related but different

Answer 6

the more heated an object is there higher the temperature the object will have. temperature is ameasurment of KE while heat is flow of energy

Question 7

9.

Answer 7

Celsius, Fahrenheit, and Kelvin.
everywhere but United States, Belize, Palau, the Bahamas and the Cayman Islands. kelvin= science

Question 8

10.

Answer 8

With an increase in temperature, the particles gain kinetic energy and move faster.removes energy thus making the particles less active and allowing the bonding forces to take hold within the substance.

Question 9

11

Answer 9

When heated, the molecules of the liquid in the thermometer move faster, causing them to get a little farther apart.

Question 10

12

Answer 10

alcohol can evaporate, alcohol is less hazardous, Mercury is harder to read and accurate.

Question 11

13

Answer 11

due to thermal expansion. Thermal expansion is the tendency of matter to change in shape, area, and volume in response to a change in temperature..

Question 12

14

Answer 12

fire alarms. timers, thermometers, temperature sensitive switches.

Question 13

15

Answer 13

Pyrometer

Question 14

16

Answer 14

be used for leak detection
to check the quality of refractory linings.

Question 15

17

Answer 15

Freezing water to make Ice cubes. energy was removed
# When I take hot showers the steam turns back to water. losing energy
# melting butter into a liguid. energy added

Question 16

18

Answer 16

the heat energy is transferred to the molecules of water, which begin to move more quickly. Eventually, the molecules have too much energy to stay connected as a liquid

Question 17

19

Answer 17

from a liquid to a gas

Question 18

20

Answer 18

The particles would gain energy in move around and start to expand and create cracks

Question 19

What is thermal pollution

Answer 19

The dusgrading of water due to the change of ambient water temperature

Question 20

24

Answer 20

Radiation. Sun. Burning food. Burning fire. Friction
