Question

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

Answer #1

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

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

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

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

determine the heat required to be added to change 47 kg of water
at 100 degrees Celsius to steam at 100 degrees Celsius.

Suppose that 100.0 g of ice at 0 degrees Celsius are added to
300.0 g of water at 25.00 degrees Celsius. Is this sufficient ice
to lower the temperature of the water to 5.00 degrees Celsius and
still have ice remaining? Calculate the energy (heat), which must
be removed from water to achieve the desired temperature change,
and then prove that there is (is not) sufficient ice to cool the
water. Use the specific heat capacity of water (4.184 J/g-*C)...

A 9 kilogram block of ice is to be heated from -36 Celsius to
140 Celsius.
How much energy is required to heat the ice from -36 to 0
Celsius?
How much energy is required to change the 0 Celsius ice into 0
Celsius water?
How much energy is required to heat the water from 0 Celsius to 100
Celsius?
How much energy is required to change the 100 Celsius water into
100 Celsius steam?
How much energy is required...

Calculate the amount of heat necessary to change 200.0 g of ice
at -15.0◦C to steam at 110◦C. Is this process endothermic or
exothermic?
