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

Expert Solution
As heat capayof vessel is given so we can ignore it rather we have to consider it. Please forgive me for any calculation mistake and do comment for any short of queries.
Please give thumbs up if you liked my efforts.

There are two methods A and B for studying the latent heat of
ices. The following are the collected data of the heat absorption
when the ices absorbed heat and their temperature increased from
initial -0.72℃ to temperature 0℃: Method A : 79.98, 80.04, 80.02,
80.03, 80.03, 80.04, 80.04 79.97, 80.05, 80.03, 80.02, 80.00, 80.02
Method B: 80.02, 79.94, 79.97, 79.98, 79.97, 80.03, 79.95, 79.97
Assume these data follow normal distribution with equal variance.

Dry ice is solid carbon dioxide. Instead of melting, solid
carbon dioxide sublimes according to the following equation:
CO2(s)→CO2(g). When dry ice is added to warm water, heat from the
water causes the dry ice to sublime more quickly. The evaporating
carbon dioxide produces a dense fog often used to create special
effects. In a simple dry ice fog machine, dry ice is added to warm
water in a Styrofoam cooler. The dry ice produces fog until it
evaporates away,...
