Question

How
much heat is needed to bring 30 kg of ice at -8 degrees celsius to
steam at 125 degrees celsius?

Answer #1

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?

In an experiment, 15.0g of ice at -30 degrees Celsius is
converted into steam with a temperature of 115 degrees Celsius. How
much energy (in kJ) is required for this process?

a 20 kg block of ice is heated from -20 degrees
Celsius to -2 degrees Celsius. how much heat does it absorbed
during the heating

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

How much heat is needed to convert 10 kg of water at 30◦C
to:
(a) water at 100◦C?
(b) steam?
(c) ice?
Take:
Specific heat capacity of water = 4.186 kJ/kg◦C
Latent heat of vaporization of water = 2264 kJ/kg
Latent heat of fusion of water = 333 kJ/kg.

What quantity of heat is needed to convert 5 kg of ice at -19
degrees C to steam at 100 degrees C?
Heat = 13590000 Joules -wrong

determine the heat necessary to convert 3.00kg of
steam at 150 degrees Celsius into ice at -10 degrees Celsius

How much heat is required to change 100 g of ice at –10 degrees
C to 150 degrees Celsius steam? A. 74.9 kcal B. 54 kcal C. 749 cal
D. 594 cal

How much heat is needed to convert 1 kg of ice at 0C to 1 kg of
water vapor at 100C?

Your hot chocolate is served at 90 deg Celsius, too hot to
drink. How much ice should you add to bring it to a more reasonable
temperature of 30 degrees C? The specific heat of milk is 4 J/g/deg
C, the specific heat of water is 4.19 J/g/deg C, and the latent
heat of fusion of ice is 334 J/g.
