What usually happens in general for a gas at a constant volume?
The gas volume become constant when the pressure is increased to a point that makes the distance between the gas molecules equal to zero at this point no more increase of temperature with pressure is observed. Or if the pressure and temperature are kept constant within a system then the volume can also be constant as long as you are able to maintain the pressure and temperature at constant level.
What is the constant variable for the moldy bread experiment?
The constant variable for a moldy bread experiment could be the type of bread used, the temperature at which the bread is stored, or the humidity levels in the environment. These variables are kept constant to ensure that any observed differences in mold growth can be attributed to the independent variable being tested.
What is your controlled variables of a lemon?
Some controlled variables when using a lemon for an experiment could be its size, ripeness, temperature, and the method of extraction of the lemon juice. These variables should be kept constant throughout the experiment to ensure that any changes observed are due to the manipulated independent variable and not these controlled variables.
Why is an increase in temperature observed on mixing chloroform with acetone?
Upon mixing chloroform with acetone, an increase in temperature is observed due to an exothermic reaction between the two solvents. This reaction occurs because chloroform and acetone have different intermolecular forces, leading to a release of energy when they mix.
What are the controlled parts of a controlled experiment?
The controlled parts of a controlled experiment are the variables that are kept constant or unchanged throughout the course of the experiment. These include factors such as temperature, time, lighting, and any other conditions that could potentially affect the outcome of the experiment. Controlling these variables helps to ensure that any changes observed in the experiment are a result of the manipulated variable being tested.

Who showed that other galaxies existed and observed that the univeres is expanded?
Edwin Hubble
Why temperature is constant for castigliano theorem?
Castiglino's Theorem uses the principle of minimum potential energy to find an equation or system of equations for the deflection of a configuration. Therefore, the energy of the system must be constant during the analysis. When a temperature change is observed, the system absorbs energy from the surrounding resulting in thermal expansion.
How do you observed temperature?
watch the thermometer
What is the constant variable for the moldy bread experiment?
The constant variable for a moldy bread experiment could be the type of bread used, the temperature at which the bread is stored, or the humidity levels in the environment. These variables are kept constant to ensure that any observed differences in mold growth can be attributed to the independent variable being tested.
What are two variables that must be kept constant for this experiment?
In an experiment, variables that must be kept constant are called control variables. Two common examples include temperature and pH levels. These variables should be kept constant to ensure that any changes observed in the dependent variable are a result of the independent variable being tested.
What is it called when the volume of a gas increases and the pressure decreases?
Charles' Law says that as pressure on a gas decreases, its volume increases. Charles' Law is an example of an inverse relationship.t It is not Charle's law It is Boyle's law Charles law states at constant volume, pressure is proportional to kelvin temperature And at constant pressure volume is proportional to kelvin temperature But Boyle's law states that at constant temperature pressure is inversely related to volume
If you wanted to predict how temperature will effect the volume of a gas what factors must be held constant?
If temperature increases, then pressure increases. Temperature measures the average speed of particles, so if the temperature is high, then the particles are moving quickly and are colliding with other particles more forcefully. Pressure is defined as the force and number of collisions the particles have with the wall of its container. So if the high temperature causes the particles to move quickly, they are going to collide more often with the container, increasing the pressure. This remains true as long as the number of moles (n) remains constant.
What is the lowest temperature observed in universe?
The lowest temperature ever observed in the universe is around 2.7 Kelvin (-270.45 degrees Celsius), known as the temperature of the cosmic microwave background radiation, which is a remnant from the Big Bang. It represents the average temperature of space.
What happens first in Charles apex?
In Charles' Law, the volume of a gas is directly proportional to its temperature, if pressure and amount of gas are held constant. As the temperature of a gas increases, its volume expands and vice versa. This relationship was observed by French scientist Jacques Charles in the late 18th century.
Does the temperature of a body depend on the frame from which it is observed?
No, the temperature of a body does not depend on the frame from which it is observed. Temperature is an intrinsic property of an object that does not change based on the observer's frame of reference.
What term is defined as something that occurs the same way very time it is observed?
A phenomenon that occurs the same way every time it is observed is known as a constant.
