Properties Of Matter

Question 1

Pressure

Answer 1

Pressure is a measurement of the force applied per square meter. P=F/A. Measured in Pascals - Pa

Question 2

Pressure and temperature

Answer 2

When heated the particles move faster and have a greater ammount of kinetic energy.

Question 3

Kelvin

Answer 3

Kelvin is -273 degrees celcius, also known as absolute 0

To change from Celcius to Kelvin we:add 273. Formula = P1/T1 = P2/T2

Question 4

Pressure and volume

Answer 4

As the Volume Decreases the Pressure Increases.

Question 5

Changes of state

Answer 5

Eh=mL
Eh=energy
M=mass
L=latent heat

Question 6

Power

Answer 6

P=energy/time

Question 7

If you need to find temp and have 1 other temp and 2 other volume,what should you use?

Answer 7

V1/T1=V2/T2

Question 8

General gas equation

Answer 8

P1V1/T1=P2V2/T2

Question 9

Changes of state

Answer 9

Solid to liquid=melting. Liquid to gas=vaporisation. Gas to liquid=condensation. Liquid to solid=freezing

Question 10

Specific heat

Answer 10

Eh= cm△T. (Get cm off data sheet)
