Question

a girl has 240g of water at 50 degree centigrade .how many grams of ice at zero degree centigrade are needed to cool the water to zero degree centigrade a)100g b)140g c)150g d)58g

Answer 1

Answer 2

use heat lost by water = mass of ice * Latent heat of ice

Answer 3

in CGS
240 * 1*(50-0) = m* 80

m =150g

Answer 4

Q =m cp delta T
this formula ya used for second one ???

Answer 5

H = mass * specific Latent heat
H= M*L (symbols have standard meaning )

Answer 6

ok got it . Thank you so much ^_^
