How do you derive kirchhoff's equation thermodynamics?
Well, hello there, friend! Deriving Kirchhoff's equation in thermodynamics is like painting a happy little tree. You start by considering the change in enthalpy with respect to temperature at constant pressure. By using the definition of heat capacity at constant pressure, you can then derive Kirchhoff's equation, which relates the change in enthalpy to the heat capacity at constant pressure and the temperature change. Just remember to approach it with a calm mind and gentle brushstrokes, and you'll see the beauty of thermodynamics unfold before your eyes.
The pressure acting on 60 cubic meters of gas is raised from 236 kPa to 354 kPa The temperature is kept constant What new volume does the gas occupy?
Using Boyle's Law (P1V1 = P2V2), we can calculate the new volume of the gas. Rearranging the formula gives V2 = (P1/P2) * V1. Substituting the given values, we get V2 = (236/354) * 60 = 40 cubic meters. Therefore, the gas occupies 40 cubic meters at the new pressure.
What happens to an objects temperature when you ad heat?
When you add heat to an object, its temperature increases as the kinetic energy of its particles is raised, causing them to move around more rapidly. This increase in temperature can cause the object to expand, change state (e.g. from solid to liquid), or undergo other physical changes dependent on the material and conditions.
What is an equalibrium constant?
The equilibrium constant (K) is a measure of the extent of a chemical reaction reaching equilibrium. It is the ratio of the concentrations of products to reactants at equilibrium, each raised to the power of their respective stoichiometric coefficients. It is a crucial parameter in determining the position of equilibrium in a chemical reaction.
When does thermonuclear fusion reaction start?
In stars it starts due to the great pressure at the star's center, which compresses the hydrogen and raises temperature to a condition where fusion commences. On Earth in man made equipment such as tokamaks, the pressure is much lower and the temperature has to be raised to hundreds of millions of degC to start fusion in a plasma of deuterium and tritium
What happens to the volume of a gas when its temperature is raised and its pressure is cept constant?
Expands because there's more energy for movement.
What will happen if the pressure on a sample of gas is raised three times and it's temperature is kept constant?
If the pressure on a sample of gas is raised three times and the temperature is kept constant, according to Boyle's Law, the volume of the gas will decrease proportionally to maintain a constant temperature. This means the gas will be compressed and occupy a smaller volume.
What will happen if the pressure on a sample of gas is raised three times and its temperature is kept constant?
The volume become one third.
What relationship exits between gas pressure and temperature?
Gas pressure and temperature have a direct relationship. If the pressure is raised, then the temperature will also raise, and vice versa.
What is the assumption of Charles' law?
The volume of a given mass of gas at a constant pressure varies directly with its temperature. This means that, at constant pressures, the volume of a given mass of an ideal gas will increase or decrease by the same factor as its temperatures increases or decreases. For example, if 20 liters of a gas at 283 K was then raised to the temperature of 300 K, the volume would increase to 21.2 liters.Mathematically:V1 / T1 = V2 / T2
What happens to air when it sink?
When a parcel of air is forced downward, atmospheric pressure increases, causing the air to become compressed and therefore the temperature is also raised.
What happens to the movement molecules when their temperature is raised?
They begin to move faster. The increased temperature increases the energy of the molecule.
A quantity of a gas has an absolute pressure of 400 KPa and absolute temperature of 110 Kelvin when the temperature of the gas is raised to 235 kelvin what is the new pressure of the gas?
A : 845.46 kPa
What will happen to a real gas when the temperature is lowered and the pressure is raised?
When the temperature is lowered and the pressure is raised on a real gas, the molecules will move more slowly and be forced to be closer together. This can lead to the gas condensing into a liquid or solid, depending on how low the temperature goes and how high the pressure is increased.
Rigid container holds hydrogen gas at a pressure of 3.0 atmospheres and a temperature of 2 degrees Celsius Whatwill bethe pressure if the temperature is raised to 10 degrees Celsius?
Rigid container holds hydrogen gas at a pressure of 3.0 atmospheres and a temperature of 2 degrees Celsius. The pressure if the temperature is raised to 10 degrees Celsius will be 15 atmospheres based on the law of pressure for gas.
What happens to the solubility of salts when temperature is lowered or raised?
When temperature is lowered, the solubility of most salts decreases because the solubility of solids generally decreases with decreasing temperature. Conversely, when temperature is raised, the solubility of most salts increases as the solubility of solids typically increases with increasing temperature.
Is the vapor pressure of a liquid a linear function of temperature?
If the temperature of the liquid is raised, more molecules escape to the vapor until equilibrium is once again established. The vapor pressure of a liquid, therefore, increases with increasing temperature.
