C) Lower,
They're lower because molecular solids form IMF's such as Dipole-Dipole and H-Bonds, while Ionic bonds are much more powerful.
The medium that might be used to cool the hot liquid coming from a reactor is : ( C ) Heat exchanger
<h3>Function of the heat exchanger</h3>
Heat exchanger is used for the transfer of heat between liquids to be used in a chemical reaction, It can be used for both Cooling and heating to achieve the desired temperature.
The liquid coming from a reactor which posses a very high temperature will be passed through the heat exchanger so that its temperature will attain the required temperature for the experiment.
Hence we can conclude that The medium that might be used to cool the hot liquid coming from a reactor is Heat exchanger.

Answer: 1.67 kg
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed=
= 
(1kJ=1000J)
m= mass of substance = ?
c = specific heat capacity = 
Change in temperature ,
Putting in the values, we get:
(1kg=1000g)
Thus the mass (in kg) of the copper sample is 1.67
