Which law states that internal energy is function of Temperature?
The internal energy of the ideal gas is a function of temperature alone. This isJoule's Law.
How is the pressure and absolute temperature of a gas at constant volume related?
It is change in internal energy. If the volume of the system remains unchanged (isochoric process)then the heat given to the system is entirely utilized to increase the internal energy of that system. It is to be noted that no pressure-voulme work is done in such processes.
What is the effect of excess heat or temperature on an enzyme-?
With a lot of heat, the enzyme will be denatured meaning it will lose its shape and therefore its function.
What physical factor does the molecular velocity or kinetic energy of the gas molecule depend on?
Temperature. PV = nRT. Both sides of this equation have dimensions of energy.n = number of moles; R is the Ideal Gas Constant; and T is absolute Temperature. So for a given amount of gas, the energy is directly proportional to Temperature.
How does the volume change in an isentropic process?
The entropy of an ideal gas during an isothermal process may change because normally the entropy is a net zero. The change of on isothermal process can produce positive energy.
Which law states that internal energy is function of Temperature?
The internal energy of the ideal gas is a function of temperature alone. This isJoule's Law.
The internal energy of an ideal gas depends on?
The one and only macroscopic thermodynamic property that the internal energy of an ideal gas depends on is its temperature.

Why is the internal energy of an ideal gas is proportional to its temperature?
To prove this, we will have to use 3 equations, 2 of them related to ideal gases: (i) pV = nRT (ii) p = 1/3 d <c2> (iii) Ek = 1/2 mv2 First of all, an ideal gas has no intermolecular forces. Thus, its molecules have no potential energy. The internal energy of any system can be defined as the sum of the randomly distributed microscopic potential energy and kinetic energy of the molecules of the system. It is thus evidently clear that the internal energy of an ideal gas is entirely kinetic. (Ep being zero) So, U = 1/2 m <c2> (for an ideal gas) From (i) and (ii), <c2> = 3p/d = 3pV/m = 3nRT/m (d= m/V) Substituting in the appropriate equation, we get: U = 1/2 m (3nRT/m) U = 3/2 nRT From the above equation, it can be concluded that for a fixed mass of an ideal gas, internal energy is proportional to the thermodynamic temperature. (fixed mass such that n is constant)
What happens to the internal energy of an ideal gas when it is heated from 0C to 4C?
it increases
What temperatures is a safe core temperature for cooking food?
The ideal internal temperature for poultry is 160 degrees held for at least 30 seconds.

How to calculate helmholtz free energy for ideal gas?
F=U-TS where F is the Free energy, U is energy, T temperature and S entropy
What is the effect of excess heat or temperature on an enzyme-?
With a lot of heat, the enzyme will be denatured meaning it will lose its shape and therefore its function.
When you boil a liquid and it turns into an ideal gas where does the energy go because the temperature remains constant so kinetic energy is the same and ideal gases don't have potential energy?
It turns into latent heat - the latent heat of evaporation. This energy is recovered when the gas condenses back into a liquid.
What is the ideal temperature for African lions?
the ideal temperature is 68degrees-86degrees F
What is resistance of an ideal ammeter?
ideal ammeter has zero internal resistance
