Answer:
400 milli-rems
Solution:
As per the question;
Maximum energy of particle,
Weight, w = 1 kg
Energy absorbed, E =
Now,
Equivalent dose is given by:
1 Gy = 1 J/kg
Also,
1 Gy =
Therefore,
Dose equivalent in milli-rems is given by:
The mass of the block of ice is 2.24 kg
Explanation:
The amount of heat needed for the whole process consists of three different amounts of heat:
: the amount of heat needed to raise the temperature of the block of ice from
to
: the amount of heat needed to melt the block of ice at melting point
: the amount of heat needed to raise the temperature of the water from
to
The total amount of heat needed can be written as
where we have:
(total amount of heat required)
m is the mass of the block of ice
is the specific heat of ice
is the latent heat of fusion of ice
is the specific heat capacity of water
is the change in temperature in the 1st process
is the change in temperature in the 3rd process
Solving the equation for m, we find the mass of the block of ice:
