why is the efficiency of a calorimeter less than 100%

That simply means that some energy is lost, due to friction and other causes.

The efficiency is always less than one because some of the energy is always useless for what you want. Most wasted energy eventually turns into heat. therefore the efficiency is like a percentage with 1 being 100% a device can't be 100% efficient as some energy is wasted. To work out the efficiency of a device you need to do the total useful energy produced divided by the total energy that is inputted into the device

An efficiency factor of 1 (or 100% efficiency) is not possible due to losses that cannot be reduced to zero. These losses take the form of friction, heat loss etc.

True.

Because there is always going to be friction, the efficiency of any machine will always be less then 100 percent.

Yes, an ideal machine would have an efficiency of 100%, but no machine is ideal. Because some work is wasted in all machines, there will always be less than 100% efficiency in all machines.

less

It is always less than 100% Theoretical machines can have efficiencies of 100% but in practice there is always some energy loss Efficiencies of more than 100% are not allowed by the laws of thermodynamics!

Friction dissipates energy. It may heat the machine or its surroundings, and it's always responsible for the machine's efficiency being less than 100% . . . you always get less energy out of a machine than you put into it.

It is the output energy compared to the input energy. This will always be less than 100%

Some energy is always lost in overcoming friction which converts part of the input energy into non-productive forms such as heat or sound.

no machine has one

if a machine is not efficient, it cannot fully utilise its performance. actual performance = efficiency x possible performance efficiency = actual performance / possible performance efficiency is always a decimal number less than 1, as no machine is perfect in terms of efficiency

The relationship between friction and the efficiency of a machine is when friction increases, efficiency decreases, and vice versa. That is why you can never have 100% efficiency, because there is always at least a little friction. They are inversely proportional, meaning, higher friction equals less efficiency.
