Question

How much heat is necessary to change 335 g of ice at -20°C to water at 20°C?

Answer #1

How much heat is required to change a 48.4 g ice cube from ice
at -11.5°C to water at 72°C? (if necessary, use cice=2090 J/kg°C
and csteam= 2010 J/kg°C)
How much heat is required to change a 48.4 g ice cube from ice
at -11.5°C to steam at 116°C?

1. How much heat is required to change a 32.3 g ice
cube from ice at -10.6°C to water at 47°C? (if necessary, use
cice=2090 J/kg°C and csteam= 2010 J/kg°C)
2. How much heat is required to change a 32.3 g ice
cube from ice at -10.6°C to steam at 111°C?

Part A:
How much heat is required to change a 37.9 g ice cube from ice
at -14.1°C to water at 30°C? (if necessary, use cice=2090 J/kg°C
and csteam= 2010 J/kg°C)
Part B:
How much heat is required to change a 37.9 g ice cube from ice
at -14.1°C to steam at 112°C?

A) How much heat is required to change a 44.4 g ice cube from
ice at -13.2 degrees Celsius to water at 80 degrees Celsius? (If
necessary, use c of ice= 2090 J/kg degrees Celsius and c of steam=
2010 J/ kg degrees Celsius) B) How much heat is required to change
a 44.4 g ice cube from ice at -13.2 degrees Celsius to steam at 117
degrees Celsius?

How much heat must be removed from 100 g of water at 25.0°C to
change it into ice at -10.0°C? The specific heat of ice is 2090
J/kg · K, and the specific heat of water is 4186 J/kg · K. For
water LF = 334,000 J/kg and LV = 2.256 ×
106 J/kg.

The heat of fusion of ice is 335 J/g. When 40.968 g of ice at
0øC is added to 222.298 g of water at
67.978øC, what is the final temperature?

How much heat is required to change m=1kg of ice at
-6°C into water at 60°C? cw= 4190
J/kg*K (specific heat of water), Lf= 333 kJ/kg (latent
heat of fusion of ice), cice= 2100 J/kg*K

How much heat is required to convert 400 g of ice at -5 °C to
water at 5 °C?

how much heat is needed to change 0.5 kg of ice at -20°C into
steam of 120°?

To change 25 kg of ice -10°C to steam 100°C, how much heat is
required? The specific heat of water is 4.184 kJ/kg. K. The latent
heat of fusion for water at 0°C is approximately 334 kJ/kg (or 80
cal/g), and the latent heat of vaporization at 100°C is about 2,230
kJ/kg (533 cal/g).
