Water at 0°c loses 1140 calories worth of heat. how much of the water freezes? [lf= 79.7 cal/g] a) 16.8 g b) 81.5 g c) 0.002 g d) 14.3 g e) 51.0 g

option d)

Explanation:

The amount of heat required to convert the 1 g of ice at 0 degree C to 1 g water at 0 degree C is called latent heta of fusion.

H = m Lf

where,, h is the heat required, m is the mass and Lf is the latent heat of fusion

1140 = m x 79.7

m = 14.3 g

this could be newton#'s law of cooling. the cooling curve is exponential

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
