How do you calculate the heat rejected using only temperature and work?

The heat rejected can be calculated using the first law of thermodynamics equation: Q = W - ΔU, where Q is the heat, W is the work, and ΔU is the change in internal energy. If the process is isothermal (constant temperature), then ΔU is zero, and heat rejected equals work done.


What is the relationship between pressure, density, temperature, and the gas constant in the ideal gas law equation p RT?

In the ideal gas law equation p RT, pressure (p), density (), temperature (T), and the gas constant (R) are related. Pressure is directly proportional to density and temperature, and inversely proportional to the gas constant. This means that as pressure or temperature increases, density also increases, while the gas constant remains constant.


What is the value of the mu constant in the equation?

The value of the mu constant in the equation is 3.14159.


How to find density with pressure and temperature?

To find density using pressure and temperature, you can use the ideal gas law equation: density (pressure)/(gas constant x temperature). This formula relates the pressure, temperature, and density of a gas. By plugging in the values for pressure, temperature, and the gas constant, you can calculate the density of the gas.


How do you calculate density of air at NTP?

The density of air at NTP (Normal Temperature and Pressure) can be calculated using the ideal gas law equation, where density = pressure / (gas constant x temperature). At NTP, the pressure is 1 atm, temperature is 273.15 K, and the gas constant for air is 0.0821 L.atm/mol.K. Plug these values into the equation to find the density of air at NTP.

What is the equation for isothermal process?

At the boiling point the energy goes into breaking the intermolecular bonds, but the average kinetic energy stays constant and so does the temperature until all of the bonds are broken and the substance is in the vapor state.


How do you use the ideal gas law to derive the equation for the function PV for an ideal gas undergoing an isothermal process?

The ideal gas equation says that pV=nRT. p = pressure V = volume n = number of moles R = gas constant T = temperature Keeping temperature constant and presuming we don't add or subtract any of the gas, thus keeping the number of moles constant, we have: pV=constant or V=1/const. Where const. = nRT. And this gives the specific curve.


Does an increase in pressure at constant temperature increase the rate constant of a reversible reaction in both directions?

The rate constant is unaffected, as demonstrated by Arrhenius equation: k = Ae^(-E/RT) where A is the pre-exponential factor (constant for a particular reaction) E is the activation energy R is the molar gas constant T is the thermodynamic temperature However, when pressure is increased at constant temperature for a gaseous reversible reaction, the concentrations of every reactant and product increase by the SAME factor. Since Kp (pressure equilibrium constant) is to remain constant, it means that the position of equilibrium will shift in such a way so as to decrease the total number of moles of gaseous species. Note: This answer can be improved by proving the last statement using a general example which, due to lack of time, I skipped. (Although some people might get the logic!!!)


How can one calculate the equilibrium constant with temperature?

To calculate the equilibrium constant with temperature, you can use the Van 't Hoff equation, which relates the equilibrium constant to temperature changes. The equation is: ln(K2/K1) -H/R (1/T2 - 1/T1), where K is the equilibrium constant, H is the enthalpy change, R is the gas constant, and T is the temperature in Kelvin. By rearranging the equation and plugging in the known values, you can calculate the equilibrium constant at a specific temperature.


What will be the Specific heat during an isothermal process?

That's kind of a trick question. Specific heat - also known as "heat capacity" is the energy required to change the temperature by a fixed amount. In the case of an isothermal process, the temperature isn't changing. Since specific heat is defined as (δH/δT), isothermal heat capacity would be (δH/δT)T which means, in English, the change in enthalpy with a change in temperature when the temperature isn't changing... you see the problem. If δT = 0, then δH/δT = ±∞ (positive if heat is added to the system to keep the temperature constant, negative if heat was removed to keep it isothermal) You could write some equations such that the heat capacity becomes a term in the equation. What you will generally find though is that the heat capacity is multiplying a dT term and when dT is zero, that term drops out and heat capacity is irrelevant for the calculation.


Is the rate constant dependent on temperature?

Yes, the rate constant of a reaction is typically dependent on temperature. As temperature increases, the rate constant usually increases as well. This relationship is described by the Arrhenius equation, which shows how the rate constant changes with temperature.


What is the relationship between the gas constant (R), temperature (T), and the number of moles (n) in the ideal gas law equation, 3/2nRT?

In the ideal gas law equation, the gas constant (R), temperature (T), and number of moles (n) are related by the equation 3/2nRT. This equation shows that the product of the number of moles, the gas constant, and the temperature is equal to 3/2 times the ideal gas constant.

Does the temperature have to be in Kelvin for the Arrhenius equation?

Yes, the temperature in the Arrhenius equation must be in Kelvin. Temperature in Kelvin is required to ensure that the relationship between temperature and reaction rate constant is accurately represented.


Application of differential equation in temperature?

Newton's equation of cooling is a differential equation. If K is the temperature of a body at time t, then dK/dt = -r*(K - Kamb) where Kamb is the temperature of the surrounding, and r is a positive constant.


What is the relationship between pressure, density, temperature, and the gas constant in the ideal gas law equation p RT?

In the ideal gas law equation p RT, pressure (p), density (), temperature (T), and the gas constant (R) are related. Pressure is directly proportional to density and temperature, and inversely proportional to the gas constant. This means that as pressure or temperature increases, density also increases, while the gas constant remains constant.


Will affect the rate of the constant according to the Arrhenius equation changing which factors?

The rate constant in the Arrhenius equation is impacted by temperature and activation energy. Increasing temperature generally increases the rate constant as molecules have more energy to overcome activation barriers. Similarly, lowering the activation energy required can lead to a higher rate constant.
