The correct relation between $\gamma=\frac{ c _{ p }}{ c _{ v }}$ and temperature $T$ is :
γ is independent of temperature.
The specific heat ratio (γ) is the ratio of specific heat at constant pressure (Cp) to the specific heat at constant volume (Cv). In many cases, for ideal gases, the specific heat ratios (γ) are relatively constant over a range of temperatures. For most gases, the specific heat ratio is not directly proportional to temperature, so options (B), (C), and (D) are not accurate representations of the relationship. The most common behavior is for γ to remain approximately constant with changes in temperature, which corresponds to option (A).
So, the correct Option is (A): γ α T∘
Electrolysis of 600 mL aqueous solution of NaCl for 5 min changes the pH of the solution to 12. The current in Amperes used for the given electrolysis is ….. (Nearest integer).
If the system of equations \[ x + 2y - 3z = 2, \quad 2x + \lambda y + 5z = 5, \quad 14x + 3y + \mu z = 33 \] has infinitely many solutions, then \( \lambda + \mu \) is equal to:}
An ideal gas is a theoretical gas composed of a set of randomly-moving point particles that interact only through elastic collisions.
The ideal gas law states that the product of the pressure and the volume of one gram molecule of an ideal gas is equal to the product of the absolute temperature of the gas and the universal gas constant.
PV=nRT
where,
P is the pressure
V is the volume
n is the amount of substance
R is the ideal gas constant
When we use the gas constant R = 8.31 J/K.mol, then we have to plug in the pressure P in the units of pascals Pa, volume in the units of m3 and the temperature T in the units of kelvin K.
