Unit 3: Particle Model of Matter

Question 1

Word equation for density?

Answer 1

Density (Kilograms per metre cubed, kg / m ³) = mass (kilograms, kg) / volume (metres cubed, m³)

Question 2

Letter equation for density?

Answer 2

p = m / V

Question 3

Word equation for change in thermal energy?

Answer 3

Change in thermal energy (Joules, J) = mass (kilograms, kg) x specific heat capacity (joules per kilogram per degree Celsius), J / kg°C) x temperature change (degree Celsius, °C)

Question 4

Letter equation for change in thermal energy?

Answer 4

ΔE = m x c x ΔT

Question 5

Word equation for Energy?

Answer 5

Energy (Joules, J) = mass (kilograms, kg) x specific latent heat (Joules per kilogram, J / kg)

Question 6

Letter equation for Energy?

Answer 6

E = m x L
