Q1 In an air compressor the compression takes place at a constant internal energy and 50Kj of heat are rejected to the cooling water for every Kilogram of air. Calculate the work input for the compression stroke per kilogram of air?
The source of thermal energy in an internal combustion engine?
The source of thermal energy in an internal combustion engine is from the combustion of fuel (such as gasoline or diesel) inside the engine cylinders. The controlled explosion of the fuel-air mixture generates heat energy that is converted into mechanical energy to power the vehicle.
What happens to air heated by radiation?
When air is heated by radiation, the air molecules absorb the radiant energy and increase in kinetic energy, causing them to move more vigorously. This increased motion leads to expansion of the air, resulting in a rise in temperature.
How does the temperature of gas change when it is compressed if the process is adiabatic?
In an adiabatic process, the temperature is increased when it is compressed. There is an increase in internal kinetic energy, and because temperature is related to kinetic energy, it is also increased.
What gas is increased in the air you breath out?
Carbon dioxide is increased in the air you breathe out. Our bodies produce carbon dioxide as a waste product of the energy-making process, known as cellular respiration, and this gas is exhaled through the lungs.
When air is quickly compressed why is the temperature of air increased?
When air is quickly compressed, the air molecules are forced closer together, increasing their kinetic energy and resulting in higher temperatures. This is because the work done in compressing the air increases the internal energy of the air molecules, leading to a rise in temperature.
How can the enthalpy of air be calculated?
The enthalpy of air can be calculated using the equation: enthalpy internal energy pressure volume. This equation takes into account the internal energy of the air and the pressure and volume of the system.
What is internal energy reserve in humans?
In humans, the internal energy reserve refers to the energy stored in the form of glycogen in the liver and muscles, as well as adipose tissue (body fat). This energy reserve is utilized during times of fasting or increased energy demand to provide fuel for metabolic processes and physical activity.
What type of energy is generate by internal combustion engine?
Internal combustion engines generate mechanical energy through the controlled explosion of fuel and air inside the engine's cylinders. This mechanical energy is then converted into kinetic energy to power the vehicle.

What type of potential energy does a hot air balloon have?
A hot air balloon has potential energy in the form of gravitational potential energy. As the balloon rises in the air, it gains potential energy due to its increased height above the ground. This energy can be converted into kinetic energy as the balloon descends back to the ground.
What is the Principle of Loudspeaker?
Electric energy cause a membrane to move by turning into mechanical energy. The movement of the membrane causes the air pressure to besequentially increased and rarefied. This "train" of increased and rearefied air pressure propagates into the room, and if it strikes our ear drums we perceive it as sound.
What happens to air heated by radiation?
When air is heated by radiation, the air molecules absorb the radiant energy and increase in kinetic energy, causing them to move more vigorously. This increased motion leads to expansion of the air, resulting in a rise in temperature.
When 430 J of work is done on a system it lost 120 J energy as heat Calculate the value of internal energy change for this process?
The first law of thermodynamics requires that energy input must equal energy output plus energy accumulation. In this case that translates to; 430 J = 120 J + (internal energy change) so Internal energy change = 430 J - 120 J = +310 J (the internal energy increased by 310 Joules)

How does a ball get pumped up by the sun if it is left outside?
If a soccer ball that is otherwise able to hold its pressure fairly well is heated by the sun, it will, indeed, increase its pressure. Thermal energy is transferred to the air (which is already compressed) inside the ball, and it causes the gas atoms and molecules to increase their thermal energy. This thermal energy causes increased vibration and increased "bouncing around" among the heated gas particles. The increased kinetic energy added to the air by the heat of the sun has increased the pressure in the ball.
