Answer:
It is enough
Explanation:
To develop the problem it is necessary to take into account the concepts related to the coefficient of performance of a pump.
The two ways in which the performance coefficient can be expressed are given by:
Where,
High Temperature
Low Temperature
And the other way is,
Where 
is heat rate and W the power consumed.
We have all our terms in Celsius, so we calculate the temperature in Kelvin
The rate at which heat is lost is:
The power consumed by the heat pump is
And the coefficient of performance is
With this value we can calculate the Power required,
<em>The power consumed is consumed is 5kW which is more than 2.07kW so this heat pump powerful enough.</em>

Answer:
Potentiation, habituation, and sensitization are three ways in which stimuli in the environment produce changes in the nervous system.
Answer:
D. will decrease slightly in volume when heated to 6° C
Explanation:
Answer:
Option 4
Explanation:
During heating actually heat transfer takes place from a body at higher temperature to a body at lower temperature and the heat transfer takes place until both attain the same temperature
Therefore heat transfer depends on the temperature of the systems
Now while comparing the thermal energies of the systems, if both the systems have same mass then the system which is at higher temperature has greater thermal energy when compared to the system which is at lower temperature
So in this case assuming that both the systems have same mass then the energy will leave the system with greater thermal energy and go into the system with less thermal energy as the system with greater thermal energy in this case will be at higher temperature and we are considering this assumption because thermal energy not only depends on temperature but also depends on mass of the system
