Explain specific heat, latent heat of fusion and latent heat
of vaporization. Write their mathematical relation and factors upon
which it depends.
(b) 3.5 kg ice is placed at initial temperature of −12°C. How
much heat energy is required to convert this ice completely into
steam
Give your recommendation about the concept of specific
heat capacity and latent heat can
be utilized in ice- cream industry to cool the ice creams and in
cooking food in the kitchen. In the
latent heat formula, Q = ± mL, how can you make the significance of
dual sign in the formula?
How can you provide scientific justifications to prove that there
are some differences in total
cooking time in open vessels compared that with a closed vessel
like...

Explain heat transfer, latent heat and change in temperature for
the following case: Ice kept at -10 degrees C temperature turns
into water at +10 degrees C temperature upon heating.
Find the latent heat value of the melting of the ice according
to the following information:
MCvessel = 23 cal / oC
Cw = 1 cal / g.oC
Mass of water = 163g
Ice block = 18g
Primary water temperature = 23oC
The temperature of the mixture (water and ice) = 14oC
An ice “calorimeter” can be used to determine the specific heat
capacity of a metal. A piece of hot metal is
dropped onto a weighed
quantity of ice. The energy transferred from the metal to the ice
can be determined
from the amount of ice
melted. Suppose you heat a 9.36-g piece of platinum to 98.6 °C in a
boiling water bath
and then drop it onto ice
at 0.0 °C. When the temperature of the metal...
Lab report on identification of two unknown metal, based on
their specific heat capacities. The introduction must include the
purpose of the experiment, background information thermal energy,
and the law of conservation of energy. Hypothesis. Step by step
method. Materials. Variables (independent-dependant-and control)
and how to manipulate them. Safety precaution. Analysis and
conclusion.

A 40 kg block of ice begins at -40°C. The specific heat of ice
is 2090 J/kg*C and the specific heat of water is 4186 J/kg*C. The
latent heat of fusion of water is 3.3×10^5 j/kg and the latent heat
of vaporization is 2.3×10^6 j/kg. A) How much energy is required to
heat ice to the melting point, 0°C?B) How much energy is required
to heat the ice from -50°C to the melting point and melt ice?C) How
much energy...
The initial temperature of 140 g of ice is −22°C. The specific
heat capacity of ice is 0.5 cal/g·C° and waters is 1 cal/g·C°. The
latent heat of fusion of water is 80 cal/g.
a. How much heat is required to raise the ice to 0°C?
b. How much additional heat is required to completely melt the
ice after it has reached 0°C?
c. How much additional heat is required to heat the water
(obtained by melting the ice) to...
