What else can I help you with?
What happens if you heat a closed container?
Eventually it will explode because the heat causes the gas particles inside the container to accelerate and thus, create pressure by colliding with each other and the sides of the container. This pressure --> boom.
Entropy is the amount of heat a system releases?
False
Why is burning a candle a closed system?
Burning a candle is considered a closed system because the wax and wick within the candle system are confined, and the energy and matter within the system (such as heat, light, and gases emitted) do not exchange with the surroundings. The energy released from burning the candle is contained within the system, making it a closed system.
What is the enthalpy equation used to calculate the change in heat energy of a system at constant pressure?
The enthalpy equation used to calculate the change in heat energy of a system at constant pressure is H q PV, where H is the change in enthalpy, q is the heat added or removed from the system, P is the pressure, and V is the change in volume.
Is a burning candle an example of an opened system or a closed system?
A burning candle is an example of an open system because it exchanges both energy (in the form of heat and light) and mass (as the candle wax burns) with its surroundings.
When heat is added to a closed system it goes into?
The added heat in a closed system increases the internal energy of the system, which can result in an increase in temperature, pressure, or volume depending on the type of system and the material properties.
What does high pressure system yield?
It may cause heat waves or can cause dryness.
Does pressure rise when heat rises?
Heat and temperature are two different terms. Heat is the cause and temperature is the effect. So when the temperature increases then the pressure increases provided the volume remains constant. This is what we call part of Charle's law.
What is the pressure inside the pressure cooker when closed but no heating will it be equal to atmospheric pressure or not?
The pressure inside will be the same as what the atmospheric pressure was when the lid was closed as long as no heat is added or removed.
How a pressure cooker can save in cooking food and tenderizing meat faster?
it is a closed system, pressure builds from heat causing trapped steam, thus food cooks faster.
What happens if you heat a closed container?
Eventually it will explode because the heat causes the gas particles inside the container to accelerate and thus, create pressure by colliding with each other and the sides of the container. This pressure --> boom.
Why Heating a gas in a closed container will increase its pressure?
The gas molecules gain energy from the heat and so they speed up, causing the pressure to increase.
What is the difference between closed heat pipe and open heat pipe?
Pressure rises in the tube.
Why drivers are advised to decrease the pressure of their vehicle's tires when they travel during hot days?
Heat can cause gasses to expand, which means that in closed spaces like tires, the pressure can rise. If a tire's already at high pressures before, the heat may cause it to tear, or pop. Obviously, that's bad.
Does air pressure eventually cause a thermal to dissipate?
Air pressure itself does not cause a thermal to dissipate. However, changes in air pressure can affect the movement of air molecules and impact the distribution of heat in a thermal system. This can lead to changes in temperature gradients and affect the dissipation of heat.

What controls evaporator pressure in CCEV system?
In a Closed-Loop Evaporator (CCEV) system, evaporator pressure is primarily controlled by the refrigerant flow rate and the temperature of the heat source. The system uses a combination of expansion devices and pressure sensors to maintain the desired pressure by adjusting the refrigerant flow, ensuring optimal heat exchange. Additionally, the compressor's operation plays a crucial role, as it regulates the pressure by drawing vapor from the evaporator and maintaining a balance within the system.
