Which law is described by saying that doubling the absolute temperature will double the pressure of a sample of gas in a rigid container?
The law described is Gay-Lussac's Law, which states that the pressure of a gas is directly proportional to its absolute temperature when the volume remains constant. Therefore, if the absolute temperature of a gas in a rigid container is doubled, the pressure will also double, assuming the amount of gas does not change. This relationship highlights the direct correlation between temperature and pressure in gas behavior.
What would happen to the mean speed of gas if temperature is doubled?
If the temperature of a gas is doubled, the mean speed of the gas molecules will also double. This is because the average kinetic energy of the gas molecules is directly proportional to the temperature according to the kinetic theory of gases.
What type of lipid is liquid at room temperature?
Unsaturated fats, such as oils, are typically liquid at room temperature due to their structure with double bonds that prevent tight packing of molecules. In contrast, saturated fats, which have no double bonds, are usually solid at room temperature.
Why increasing temperature does not double temperature?
Increasing temperature does not double the thermal energy of a substance because temperature is a measure of the average kinetic energy of particles, not a direct representation of energy itself. The relationship between temperature and energy is not linear; for example, doubling the temperature in Celsius or Fahrenheit does not equate to doubling the kinetic energy. In thermodynamics, temperature must be considered on an absolute scale, like Kelvin, where doubling the temperature reflects a significant increase in energy, but not a simple doubling of the original temperature value.
The number of molecules in a container is tripled and the Kelvin temperature doubled The volume remains unchanged The new pressure will be how many times greater than the original pressure?
The new pressure will be six times greater than the original pressure. This is because pressure is directly proportional to the number of molecules and temperature in Kelvin, according to the ideal gas law. Since both the number of molecules and temperature have increased, the pressure will triple for the increase in molecules and double for the increase in temperature, resulting in a total increase of 6 times.
Which temperature scale does the average kinetic energy of molecules double when the temperature double?
The temperature scale that corresponds to the average kinetic energy of molecules doubling when the temperature doubles is the Kelvin scale. In the Kelvin scale, 0 K represents absolute zero where molecular motion ceases, making it directly proportional to the average kinetic energy of molecules.
Does doubling celsius temperature double pressure?
Using the Celsius temperature scale, it is not correct. But doubling the temperature using the Kelvin temperature scale, where zero is the absolute minimum gegree possible, will double pressure . p1/T1=p2/T2=constant.
What is the absolute value 3.7?
It is: 3.7 because a double minus becomes a plus and so --3.7 = 3.7

What temperature change would cause a sample of an ideal gas to double in volume while the pressure was held constant?
If the volume is fixed, then doubling the absolute temperature will double the pressure.At 0° C, the absolute temperature is 273 K. Heat the gas to 273° C = 546 K.
What would happen to the mean speed of gas if temperature is doubled?
If the temperature of a gas is doubled, the mean speed of the gas molecules will also double. This is because the average kinetic energy of the gas molecules is directly proportional to the temperature according to the kinetic theory of gases.
A volume of air has a temperature of 0C. an equal volume of air that is twice as hot has a temperature of?
The equal volume of air that is twice as hot would have a temperature of 20C. Temperature is directly proportional to the average kinetic energy of the air molecules, so doubling the temperature would double the kinetic energy of the molecules.
Do Charles' law indicates that an increase in absolute temperature will cause a corresponding increase in volume?
Charles's law states that at constant pressure, the volume of a given mass of an ideal gas increases or decreases by the same factor as its absolute temperature. For fixed mass of an Ideal Gas at constant pressure the volume it occupies is directly proportional to its absolute temperature. So, if you double the absolute temperature of a gas while holding its pressure constant, the volume has to double. There is no such thing as an Ideal Gas. So, doubling the temperature of a real gas will not exactly double its volume. However, the general principle hold true. If you increase the temperature of any gas at constant pressure the volume it occupies will increase.
Why aren't unsaturated fats solid at room temperature?
Unsaturated fats are not solid at room temperature because they have double bonds in their carbon chains, which create kinks in the molecules. These kinks prevent the molecules from packing tightly together, resulting in a liquid state at room temperature.
Temperature is not a measurement of the amount of heat?
True! Temperature is the average kinetic energy of the molecules of a substance.Heat is the total kinetic energy of the molecules of a substance. See the difference?For example, if you double the amount of a substance, then you have double the heat energy, but the temperature stays the same.
What type of lipid is liquid at room temperature?
Unsaturated fats, such as oils, are typically liquid at room temperature due to their structure with double bonds that prevent tight packing of molecules. In contrast, saturated fats, which have no double bonds, are usually solid at room temperature.
What happens to the volume of a gas when the temperature doubles?
In a perfectly flexible and expandable container (pressure is constant) the volume of an ideal gas will double as the absolute temperature doubles. For a non-ideal gas and non-perfect container, your results will vary but will always be somewhat less than double.
