What must remain constant for Boyle's law to be true?
1. A more correct name is Boyle-Mariotte law. 2. Only the temperature must remain constant.
If the temperature of a reaction increases what happens to the value of the equilibruim constant?
Equilibrium constant changes when temperature changes. For an endothermic reaction, the equilibrium constant increases with temperature while for an exothermic reaction equilibrium constant decreases with increase in temperature. Equilibrium constants are only affected by change in temperature.
When does raising the temperature of gas increase its pressure?
Raising the temperature of a gas increases its pressure when the volume of the gas is kept constant. This is described by the ideal gas law, which states that pressure is directly proportional to temperature when volume is constant. When the temperature of a gas is increased, the average kinetic energy of the gas particles increases, leading to more frequent and forceful collisions with the walls of the container, resulting in higher pressure.
What remains constant in the combined gas law?
Combined gas law states:" The ratio between the pressure-volume product and the temperature of a system remains constant: p.V = k.T "k is a constant which only is proportionally depending on the amount of gas.
What happens to the pressure of a system when the volume is decreased if the temperature and number of gas particles are held constant according to Boyles Law?
According to Boyle's Law, if the volume of a gas is decreased while keeping the temperature and number of gas particles constant, the pressure of the gas will increase. This is because there is less space for the gas particles to occupy, leading to more frequent collisions with the walls of the container, resulting in an increased pressure.
What is the main objection of ohm's law in measuring resistance?
Temperature. Ohms law is applicable to measure resistance of an element at constant temperature only.
Why ohms law is valid only for constant temperature and constant pressure?
Ohm's Law is valid for constant temperature because it assumes a fixed relationship between voltage, current, and resistance. Any changes in temperature can alter the resistance of the material, affecting the accuracy of the law. Additionally, Ohm's Law is only valid for constant pressure because pressure changes can affect the physical properties of the material, such as its conductivity, which can also impact the law's accuracy.

What is the significance of the constant temperature reference in ohms law?
As temperature affects resistivity, the resistance of a conductor may change if its temperature is allowed to increase. For pure metal conductors, the resistance generally increases as the temperature increases.Ohm's Law ('the current flowing along a conductor, at constant temperature, is directly proportional to the potential difference across that conductor') only applies when the resistance of the conductor is constant so, when verifying Ohm's Law, the temperature must be kept constant, in order to keep the resistance constant.It should be pointed out that the ratio of voltage (U) to current (R) is called resistance (R), and the resistance of a circuit can be found from the equation, R = U/I whether Ohm's Law applies or not -but Ohm's Law itself only applies when the ratio is constant over a range of voltage variation.
Specific rate constant?
specific rate constant is an experimentally determined proportionality constant which is different for different reactions and changes only with temperature.
Why does the temperature remain constant when it boils?
A substance has different phases, but it only boils at a certain temperature. If it is over that temperature it will evaporate or if it is under that temperature it won't boil.
How do you differentiate between reaction rate and specific rate constant?
The reaction rate is the rate at which the moles of substance change that varies with both temperature and concentration of the reactants. The specific rate constant is a proportionality constant that will vary only with temperature.
If the temperature of a reaction increases what happens to the value of the equilibruim constant?
Equilibrium constant changes when temperature changes. For an endothermic reaction, the equilibrium constant increases with temperature while for an exothermic reaction equilibrium constant decreases with increase in temperature. Equilibrium constants are only affected by change in temperature.
What is constant in ohms law?
Ohm's original law was 'The potential difference across a conductor is proportional to the current flowing through it, provided physical conditions such as temperature remain constant.'Today Ohm's law is expressed as E = IR or sometimes V = IR,the units being Volts, Amps and Ohms.AnswerOhm's Law ('the current flowing along a conductor, at constant temperature, is directly proportional to the potential difference across that conductor') only applies when the resistance of the conductor is constant so, when verifying Ohm's Law, the temperature must be kept constant, in order to keep the resistance constant.It should be pointed out that the ratio of voltage (U) to current (R) is called resistance (R), and the resistance of a circuit can be found from the equation, R = U/I whether Ohm's Law applies or not -but Ohm's Law itself only applies when the ratio is constant over a range of voltage variation.

Is ohms law only for resistive network?
Absolutely
What happens to the pressure of a gas if the volume of gas is tripled at a constant temperature?
If the volume of a gas is tripled at constant temperature, according to Boyle's Law, the pressure of the gas will decrease by a factor of 3. This is because pressure and volume are inversely proportional at constant temperature.
