The amount of heat required to raise the temperature is 706.05J.
To find the answer, we need to know more about the specific heat capacity.
<h3>How to find the heat required to raise the temperature?</h3>
- Specific heat can be defined as, the amount of heat needed to increase a substance's temperature by one degree for every gram.
- We have the expression for amount of heat required to raise the temperature from T1 to T2 as,
Q=msΔT
- We have given with the following values,
- Thus, the amount of heat required to raise the temperature is,
Thus, we can conclude that, the amount of heat required to raise the temperature is 706.05J.

Answer:
Explanation:
Given data
Initial temperature of air Ti=300 K
Vf (final volume of air)=2Vi (initial volume of air )
To find
Final temperature
Solution
Since no energy is lost by thermal conduction during the process we categorize this process as an adiabatic one.Hence we apply;
Where air is predominantly a diatomic gas Y=1.4m
Substitute the given values
So
Answer: That's air resistance.
Explanation: Well, air resistance is an upward force exerted on falling objects.

Answer:
The nail will stick to the bar magnet because it will become magnetized, and it's metal. The presence of the nearby north pole rearranges the magnetic domains inside the steel so that their south poles all point toward the north pole of the permanent magnet. As a result, the other end of the nail becomes a north pole.Magnets attract iron due to the influence of their magnetic field upon the iron. ... When exposed to the magnetic field, the atoms begin to align their electrons with the flow of the magnetic field, which makes the iron magnetized as well. This, in turn, creates an attraction between the two magnetized objects.
