If the star Antares has a peak wavelength of 700NM then its surface temperature is about?
Using Wien's displacement law, we can estimate the surface temperature of Antares by converting the peak wavelength from nanometers to meters and then using the formula T = 2.898 x 10^6 / λ, where T is the temperature in Kelvin and λ is the wavelength in meters. Plugging in the values, we get T ≈ 4143 K.
Does ohm's law also apply to the filament lamp?
No. For Ohm's Law to apply, the ratio of voltage to current must remain constant for variations in voltage. This simply doesn't happen with a tungsten filament. In fact, MOST materials don't obey Ohm's Law.
Which gas law has the assumptions of a fixed amount and a fixed temperature of a gas?
The ideal gas law has the assumptions of a fixed amount and fixed temperature of a gas. It relates the pressure, volume, and temperature of a gas through the equation PV = nRT, where P is pressure, V is volume, n is the number of moles of gas, R is the gas constant, and T is temperature.
When pressure increases temperature increases?
In general, as pressure increases, the temperature of a gas will also increase due to the increased kinetic energy of the gas molecules. This relationship is described by the ideal gas law, which shows that pressure and temperature are directly proportional when volume and amount of gas are constant.
Identify the gas law that is used to describe gas behavior under a specific set of circumstances.?
Charles' Law and other observations of gases are incorporated into the Ideal Gas Law. The Ideal Gas Law states that in an ideal gas the relationship between pressure, volume, temperature, and mass as PV = nRT, where P is pressure, V is volume, n is the number of moles (a measure of mass), R is the gas constant, and T is temperature. While this law specifically applies to ideal gases, most gases approximate the Ideal Gas Law under most conditions. Of particular note is the inclusion of density (mass and volume) and temperature, indicating a relationship between these three properties.The relationship between the pressure, volume, temperature, and amount of a gas ~APEX
Why must temperature always be in units of kelvin before using Charles law?
Temperature must be in Kelvin when using Charles's Law because it is an absolute temperature scale that starts at zero Kelvin, where molecular motion theoretically stops. Since Charles's Law involves the ratio of volumes and temperatures, using the Kelvin scale ensures consistency and accurate results in the calculations.
Is temperature expressed on the Celsius scale in calculations using Charles' Law?
Yes, temperature is typically expressed in Celsius when using Charles' Law, as the relationship between volume and temperature is directly proportional. It is important to ensure that the temperature is measured in Kelvin when using the ideal gas law.
What temperature scale must be used in Charles Law problems?
The temperature scale that must be used in Charles' Law problems is the Kelvin scale. This is because Charles' Law relates the volume of a gas to its temperature in Kelvin, and temperature must be in Kelvin to ensure a direct relationship between volume and temperature.
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.
What is Charless Laws?
Charles' Law states that there is a direct mathematical relationship between volume and temperature of a gas.
The volume of a gas must increase?
To increase the volume of a gas, either the temperature must rise or the pressure must decrease, according to Boyle's Law and Charles's Law. This relationship is known as the ideal gas law, which states that the volume of a gas is directly proportional to its temperature and inversely proportional to its pressure.
According to Charless law whenever the temperature of a gas at constant pressure decreases the volume increases.true or false?
Answer: No, this is not according to Charles law; however according to Boyles law this statement is correct ('true').Charles' law states: When the pressure on a sample of a gas is held constant, the Kelvin temperature and the volume will be directly related.Boyle's law describes how the pressure of a gas tends to decrease as the volume of a gas increases when temperature is held constant.
What two factors must be constant with boyle's law?
According to Boyle's law, temperature and amount of gas must be constant. This means that as pressure and volume change, temperature and amount of gas should remain the same for the law to hold true.
The temperature scale for using Charles' Law is not Fahrenheit or Celsius but what?
Always use temperature in the Kelvin scale when doing gas law problems.
Which variables must be kept constant for Boyle's law to hold?
Temperature and the amount of gas (moles) must be kept constant for Boyle's law to hold true. This means the pressure and volume of a gas are inversely proportional provided the temperature and amount of gas remain constant.
Which factors must be constant Boyle's law?
n= no. of moles and t=temperature
When using the ideal gas law which temperature measurement should be used?
When using the ideal gas law, the temperature measurement should be in Kelvin. This is because the ideal gas law requires an absolute temperature scale for accurate calculations, and Kelvin is an absolute temperature scale where 0 K represents absolute zero.
