According to Ohm's law if V is constant?
Ohm's Law describes the relationship between the voltage (potential difference) across the ends of some conductors and the resulting current through those conductors for variations in voltage. If the voltage is constant, then Ohm's Law is irrelevant.
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.
Which states that the ratio of voltage to current in a material is constant which is the resistance of the material?
Ohm's Law
Using Ohm's Law explain how voltage changes in relation to current assuming that resistance remains constant?
how do you use ohms law express conductance in terms of current and voltage?
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.
What is the Henry's law constant for Carbon Dioxide at 20 degrees Celsius?
Henry's law constant for Carbon Dioxide at 20 degrees Celsius is: 1,6*10^3 ATM
What volume is occupied by 2.0g He at 25 degrees celsius and 775 mmHg?
A fixed quantity of gas at a constant pressure exhibits a temperature of 27 degrees Celsius and occupies a volume of 10.0 L. Use Charles's law to calculate: the temperature of the gas in degrees Celsius in atmospheres if the volume is increased to 16.0 L
Do this with degrees Celsius in solving problems with Charles law?
convert
A sample of Xenon gas at 20degree Celsius and 0.570 ATM is cooled to a pressure of 0.100 ATM If the volume remains constant What is the final Celsius temperature?
Using the ideal gas law, we can calculate the final temperature of the Xenon gas. Since the volume remains constant, we can use the combined gas law (P₁/T₁ = P₂/T₂) to solve for the final temperature. Rearranging the equation gives T₂ = (P₂ / P₁) * T₁. Plugging in the values, we get T₂ = (0.100 / 0.570) * 20 degrees Celsius = 3.51 degrees Celsius.
Does steam at 100 degrees celsius obeys Boyle's Law?
Yes it does
A tire has a pressure of 325 kPa at ten degrees Celsius. If the temperature rises fifty degrees Celsius and the volume remains constant what is the new pressure?
Use the ideal gas law: P1/T1 = P2/T2. Rearrange the equation to solve for P2: P2 = (P1/T1) * T2. Plug in the values: P2 = (325 kPa / 283 K) * 60 degrees Celsius. Convert the temperature to Kelvin: 60 degrees Celsius + 273 = 333 K. Calculate the new pressure: P2 ≈ 361 kPa.
Two identical blocks of iron one at 10 degrees celsius and the other at 20 degrees celsius are put in contact suppose the cooler block cools to 5 degrees celsius and the warmer block warms to 25?
Violation of 2nd Law
When using Charles law the units of temperature can be either Kelvin or degree Celsius?
Yes, that is correct. Charles's Law states that the volume of a gas is directly proportional to its temperature, assuming pressure and amount of gas are constant. The temperature can be measured in Kelvin or degrees Celsius because they both have the same unit size and are related by a simple conversion factor (Kelvin = Celsius + 273.15).
What is the volume of the gas at 250 degrees Celsius as compared with the volume at 0 degrees Celsius?
P1V1/T1 = P2V2/T2Assuming only temperature and volume are changing and pressure will be kept constant:V1/T1 = V2/T2Only Kelvin can be usedV1/273 = V2/523Assume the volume at 0 ºC is 1 unit thenV2 = 1.92 units
What happens to volume if the temperature of a gas is decreased from 60 degrees Celsius to 30 degrees Celsius?
The volume of the gas will decrease. The gas molecules move faster when they are warmer, because more heat equates to more energy. The faster they move, the more space they will take up and the greater the volume. Therefore, if the temperature goes down, they have less energy and take up less space. This is shown in the ideal gas law: PV = nRT P = Pressure of the gas V = Volume n = mols of the gas R = ideal gas constant (8.314 J/molK) T = Temperature As you can see, if temperature is decreased and only pressure is allowed to change, with all other variables remaining constant, volume will also have to decrease to maintain the proportion.
When the pressure on a gas increases at constant temperature its volume?
decreases
When ice melts at 0 degrees Celsius is it a theory or law?
The fact that ice melts at 0 degrees Celsius is a physical law known as the melting point of ice. It is a well-established and observable phenomenon in nature that has been consistently verified through experimentation.
