View Full Interview# Is hydrogen gas an ideal gas?

Yes, hydrogen gas is an ideal gas. The ideal gas doesn't exist; it is only a theoretical concept. And generally ideals are only illusions.

# 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

# If 400 joules of heat are added to a gas in an isochoric process what is the change in its internal energy?

400 joules.

# What happens to the internal energy of an ideal gas when it is heated from 0 Celsius to 4 Celsius?

It increases. hope this helps xx :)

# 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 mv2First of all, an ideal gas has no inter…molecular 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 nRTFrom 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)

# The internal resistances of an ideal voltmeter and ideal ammeter are?

The internal resistance of an ideal voltmeter is infinity ohms. The internal resistance of an ideal ammeter is zero ohms.Since there are no ideal voltmeters or ammeters, we co…nsider the error introduced by adding these instruments to various circuits. In general, practical meters have high enough impedance (voltage) or low enough impedance (current) to not affect the reading more than the instruments accuracy specification, or to not affect the circuit more than is considered acceptable. There are times when this is not true, so we always consider the instrument and its contribution to systemic error.

# An ideal gas is an imaginary gas?

That conforms to all of the assumptions of the kinetic theory

# The internal resistance of an ideal ammeter?

0. An ammeter is placed in series with the circuit in question; if its' internal resistance is high, it will change the current flow, thus making the measurement meaningless.F…or the same reason an ideal voltage meter will have infinite resistance.

# What happens to the internal energy of an ideal gas when it is heated from 0 degrees celsius to 4 degrees celsius?

If it's not allowed to expand, then its internal energy increases by about 1.46% .

# Is argon gas an ideal gas?

Strictly speaking no, as an ideal gas is simply a theoretical device. Though it can be treated as an ideal gas to an extent.

# What is the ideal internal resistance of galvanometer?

zero

# What 3 ideals are mutually dependent and guide?
