What 2 things can make the pressure of gas rise?
1) Increase in heat 2)Decrease in volume
What is the dependent variable in an experiment that shows how the volume of gas changes in temperature?
The dependent variable in this experiment is the volume of gas. This is because it is the outcome that is being measured and is expected to change based on the independent variable, which is the temperature.
What law states that volume and temperature are directly related?
The law that states that volume and temperature are directly related is known as Charles's Law. It asserts that, at constant pressure, the volume of a gas is directly proportional to its absolute temperature (measured in Kelvin). This means that if the temperature of a gas increases, its volume also increases, provided the pressure remains unchanged. Conversely, if the temperature decreases, the volume decreases as well.
If the temperature and volume of a gas changes what else will change?
Volume ChangesThe volume of any solid, liquid, or gas will change with changes in temperature.
Find the change in volume of an aluminium sphere of 0.4m radius when it is heated from 0 to 100degree centigrade?
The change in volume of an object due to temperature change is given by the coefficient of volume expansion (α), which for aluminum is about 0.000023 per degree Celsius. Given the initial temperature change from 0 to 100 degrees Celsius, the total change in volume can be calculated using the formula: ΔV = V * α * ΔT, where V is the initial volume, α is the coefficient of volume expansion, and ΔT is the change in temperature. Substituting the values, you can find the change in volume of the aluminum sphere.
What is the purpose of a thermobarometer in a volumeter?
A thermobarometer in a volumeter is used to measure both temperature and pressure, which are important factors in determining the volume of a substance. By taking into account temperature and pressure, the volumeter can accurately calculate the volume of the substance being measured.
When is pressure useful?
when determining volume, moles, weight, and/or temperature
How does temperature affect s thermometer?
Temperature affects a thermometer by causing the liquid or material inside to expand or contract, leading to a change in volume. This change in volume is measured by the scale on the thermometer, so as temperature increases or decreases, the level of the liquid or material inside the thermometer will rise or fall accordingly.
How can you change the volume of a liquid?
- by the variation of the temperature- by the variation of the pressure
What are volume and mass properties of?
Volume is the amount of space an object occupies, measured in cubic units such as liters or cubic meters. Mass is the amount of matter in an object, measured in units such as grams or kilograms. Volume and mass are independent properties of an object, with mass determining how much weight an object has and volume determining how much space it takes up.
What physical property can be measured?
Physical properties that can be measured include mass, volume, density, temperature, and conductivity.
How do you measure the density of a gas?
The density of a gas can be measured by determining its mass per unit volume. This is typically done by measuring the gas's pressure, temperature, and volume and using the ideal gas law to calculate the density. Alternatively, specialized instruments such as densitometers can be used for more accurate measurements.
What are some examples of Charles' Law problems and how can they be solved?
Examples of Charles' Law problems include determining the final volume or temperature of a gas when its initial volume and temperature are known, or calculating the change in volume or temperature when pressure is held constant. These problems can be solved using the formula V1/T1 V2/T2, where V1 and T1 are the initial volume and temperature, and V2 and T2 are the final volume and temperature. By rearranging the formula and plugging in the given values, the unknown variable can be calculated.
What can be measured in the metric system?
Weight, length, temperature, volume, land area.
Why do solids change their volume?
it cannot change its volume because it has a definite shape and the electrons are tightly packed but it can change its volume when there is a slight change in temperature.

How does volume of matter change with increase in temperature?
Assuming that pressure and the amount of matter are constant (meaning they do not change), volume will increase as temperature increases.
