Answer #1

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

A 100-gram metal block is initially heated to 100 degrees
Celsius. The copper block is then placed in 200-grams of water at
20 degrees Celsius. The block and the water are allowed to come to
thermal equilibrium and reach a temperature of 23.52 degrees
Celsius. a.) What is the change in temperature of the block and the
water? b.) If the specific heat of water is 4.184 J/g C, what is
the heat gained by the water? c.) What is...

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 energy is required to change a 40-g ice cube from ice
at -10 Celsius to steam at 110 Celsius?

8. A 180 g block of copper heated to 120 degrees Celsius dropped
into a 360 g aluminum calorimeter container
containing 440 g of water. If the initial temperature of the
calorimeter and the water is 20 °C,
what is the final equilibrium temperature of the system?
9. 25 g steam at 110 °C is added temperature of the resulting
water 100 g of ice at -10 °C in an
insulated container. What is the final temperature of the resulting...

A 60 kg block of ice begins at -60 degrees the specific heat of
ice is 2090 j/(kg)C. The latent heat of fusion of water is 3.3 x
10^5 and the latent heat of vaporization is 2.3 x 10^6 J/kg. How
much energy is required to heat the ice to 0 degrees Celcius
(melting point)?
How much energy is required to heat the ice from -50C to the
melting point and melt the ice?
How much energy is required to...

Consider 1 kilogram of saturated water at 70 degrees celsius in
a closed and rigid container which is heated to steam (superheated
water) at 300 degrees celsius and 5 MPa by adding 1500 kJ of
heat.
a) What is the fraction of vapour and liquid at the initial
state?
b) What is the work done as a result of the heating process?

How much energy is required to change a 55-g ice cube from ice
at 0°C to steam at 140°C? J

A 5.00 kg block of ice melts at a temperature of 0 degrees Celsius.
What is the change in entropy of the ice when changing from solid
ice to water?
be detailed pls

A block of ice (-30°C) with a mass of 1 lb is heated. How much
heat (kJ) is needed to turn the ice into stream (vapor) at 200°C?
