I think so but am not sure
You’re correct hope this helps :)
<span>Nuclear power plants produce radioactive
waste that must be stored properly. It is very impossible for a nuclear power plant
to have no waste at all since lots of chemicals are used to create the process
as it gives energy to other machines. Nuclear energy can be used to power all
of the above choices. Radioactive waste can not be released into local water
supplies since the wastes are very radioactive and may cause mutation to the
fishes and bioaccumulation which will affect humans as well. It will also cause
air pollution if the chemicals are not stored properly.</span>
Answer:
0° C
Explanation:
Given that
Mass of ice, m = 50g
Mass of water, m(w) = 50g
Temperature of ice, T(i) = 0° C
Temperature of water, T(w) = 80° C
Also, it is known that
Specific heat of water, c = 1 cal/g/°C
Latent heat of ice, L(w) = 89 cal/g
Let us assume T to be the final temperature of mixture.
This makes the energy balance equation:
Heat gained by ice to change itself into water + heat gained by melted ice(water) to raise its temperature at T° C = heat lost by water to reach at T° C
m(i).L(i) + m(i).c(w)[T - 0] = m(w).c(w)[80 - T], on substituting, we have
50 * 80 + 50 * 1(T - 0) = 50 * 1(80 - T)
4000 + 50T = 4000 - 50T
0 = 100 T
T = 0° C
Thus, the final temperature is 0° C
