Heat & Temp Keywords

Question 1

Thermometers

Answer 1

A thermometer is used for measuring temperature

Question 2

Scales

Answer 2

?

Question 3

Celsius scale

Answer 3

Andres Celsius developed the Celsius scale. He bases his scale on two properties, the boiling point and freezing point of water. Then he separated the region between these points with degrees units.

Question 4

Kelvin Scale

Answer 4

He was known as William Thompson, he invented the Kelvin scale, another way of measuring temperature.

Question 5

Absolute zero

Answer 5

Absolute zero is the point where particles stop moving (-273.15 degrees Celsius)

Question 6

Sensor

Answer 6

Each type of thermometers contains a sensor -material that is affected by changes in some feature of the environment such as temperature.

Question 7

Signal

Answer 7

?

Question 8

Water boils at LOWER temperature at high altitudes. Why?

Answer 8

Atmospheric pressure affect the boiling point

lower atmospheric pressure -lower boiling point

For example water will boil at 100°C at sea level. On top of Mount Everest, water will boil at 69°C because of lower atmospheric pressure.

Question 9

Can all thermometers measure many different types of matter?

Answer 9

No, different thermometers are best suited for different measurements.

Question 10

Thermocouple

Answer 10

Looking for heat

Hunting)thermos

Question 11

Bimetallic strip

Answer 11

Two metals

Question 12

Recording thermometer

Answer 12

Records air &/or water

Question 13

fixed volume cannot be squashed

Question 15

Liquid

Answer 15

Not rigid

no fixed shape

fixed volume cannot be squashed

Question 16

Gas

Answer 16

Not rigid

no fixed shape

no fixed volume can be squashed

Question 17

Four ideas of the particle theory of matter?

Answer 17

Pam makes space toose

P-particles
All substances are made of tiny particles

M- Motion
Particles are always in motion

S-space
All particles have space between them

T-temperature
If the temperature increases the movement of particles increases and vice versa.

Question 18

When a substance warms

Answer 18

It’s temperature increases -its particles are moving faster. When a substance cools-it’s temperature decreases and its particles are moving more slowly

Question 19

What is an Energy

what units do we use to measure energy

named after who

Answer 19

Energy is the measure of somethings ability to do work. In other words, the ability to cause change. Joules (J) named after James Jules. Joules (J) are the measurements of energy.

Question 20

Three examples of things that use energy

Answer 20

Humans
Lights
Vehicles

Question 21

Can energy be transferred from one object to another

Answer 21

Yes

Ex. a battery thats powering a flashlight

Question 22

What is thermal energy

Answer 22

Thermal energy is the energy that comes from heat. heat is generated by the movement of tiny particles in an object.

Question 23

Which way does heat energy travel from hot to cold or from cold to hot

Answer 23

Hot to cold
think of hot drinks the heat travels the hot drink to the cooler air

Energy is not a substance. it can be weighed. it does not take up space. energy describes the quality or condition.

Energy is a property or quality of an object or substance that gives it ability to move do work or cause changes

The law of conversation of energy states that energy cannot be created or destroyed it can only be transformed from one form to another or passed from one object to another
