Unit 3, particle model of matter

Question 1

What is the formula for density

Answer 1

Density = mass/ volume

Question 2

What is the formula for the change in thermal energy

Answer 2

Change in thermal energy = mass x specific heat capacity x temperature change

Question 3

What is the definition of dencity

Answer 3

The density is defined as the mass per unit volume density = mass/volume

Question 4

Density of Solids and Liquids

Answer 4

Solids and liquids have similar densities as the space between particles does not change significantly
