Method • 1

  • Measure mass of calorimeter

  • Add warm water

3
New cards

Method • 2

  • Measure mass of calorimeter + water

  • Calculate mass of water

4
New cards

Method • 3

  • Measure initial temperature

  • Add crushed and dried ice

5
New cards

Method • 4

  • Measure final temperature

  • Calculate temperature change

6
New cards

Method • 5

  • Measure mass of ice + water + calorimeter

  • Calculate mass of ice

7
New cards

Write out the formula used for this experiment

m(i) l + m(i) c(w) temp change (i) = m (w) c(w) temp change (c+w) + m(c) c (c) temp change (c+w)

Precautions • 1

Crush ice to ensure it is at 0°C

9
New cards

Precautions • 2

Dry ice to ensure there is no excess water

10
New cards

Precautions • 3

Room temperature between initial temperature and 0°C to cancel out heat gain and loss errors
