Define 3 precautions that are associated with this experiment • 1

Make sure ice is melting - latent heat at 0°C

Define 3 precautions that are associated with this experiment • 2

Crush and dry ice for no excess water

Define 3 precautions that are associated with this experiment • 3

Room temperature between initial water temperature and 0°C to cancel out errors

Write out the formula associated with this experiment

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