What else can I help you with?
When a substance undergoes a phase change it still has a definite A mass B shape C volume D temperature?
C. volume. During a phase change, the substance's volume remains constant even though there may be a change in its mass, shape, or temperature.
When you heat a cool substance does the mass or volume change?
When you heat a cool substance, typically the volume increases while the mass stays constant. This is because heating usually causes the particles in the substance to move faster, spreading out and occupying more space. However, the actual mass of the substance remains the same during this process.
What properties of a substance does not change when the amount of the substance changes 1 mass 2 volume 3 temperature?
The mass of a substance does not change when the amount of the substance changes. The temperature of a substance does not change when the amount of the substance changes. However, the volume of a substance may change when the amount of the substance changes, depending on the conditions.
How is the mass of a liquid substance affected after it boils?
When a liquid substance boils, it undergoes a phase change from liquid to gas. During this process, the mass of the substance remains unchanged, as the molecules transition from the liquid phase to the gas phase without any loss or gain of matter. However, if the gas escapes the container, the mass of the remaining liquid will decrease. Thus, the mass of the entire system depends on whether the gas is retained or allowed to escape.
When a gas is heated its mass?
The TOTAL mass of the sample stays the same, but keep in mind that you can only measure it accurately if you can keep the sample confined, which can be difficult when changing a liquid to a gas. When heating a gas, it usually expands (or increases pressure in a rigid container).
When a substance undergoes a phase change it still has a definite A mass B shape C volume D temperature?
C. volume. During a phase change, the substance's volume remains constant even though there may be a change in its mass, shape, or temperature.
The amount of heat gained or lost by a substance is equal to the product of?
mass times the temperature change rimes specific heat capactiy
In what state of matter has mass and it and it is the same each time?
Mass is a property that remains constant in all states of matter: solid, liquid, gas, and plasma. The total mass of a substance does not change when it undergoes a phase change because mass is a measure of the amount of matter in an object.
Which process would change the mass of an iron bolt?
If the iron bolt undergoes a chemical reaction, such as rusting, its mass could change. Addition or removal of material, like coating it with another substance or cutting it, could also change its mass. Otherwise, if kept under normal conditions, the mass should remain constant.
How do you calculate the heat of combustion for a given substance?
To calculate the heat of combustion for a substance, you can use the formula: Heat of combustion (mass of substance) x (heat capacity) x (change in temperature). This formula helps determine the amount of heat released when a substance undergoes complete combustion.
When you heat a cool substance does the mass or volume change?
When you heat a cool substance, typically the volume increases while the mass stays constant. This is because heating usually causes the particles in the substance to move faster, spreading out and occupying more space. However, the actual mass of the substance remains the same during this process.
How does phase change effect the mass of a substance?
A phase change does not affect the mass of a substance because mass is a constant property of matter. During a phase change, such as melting or boiling, the substance's molecular arrangement changes, but the total mass remains the same.
What properties of a substance does not change when the amount of the substance changes 1 mass 2 volume 3 temperature?
The mass of a substance does not change when the amount of the substance changes. The temperature of a substance does not change when the amount of the substance changes. However, the volume of a substance may change when the amount of the substance changes, depending on the conditions.
How does a physical such as mass or texture change without causing a change in the substance?
Ice melts to water if the temperature is high enough. This would change the texture but not the mass. It is difficult if not impossible to change the mass without changing the substance.
How is the mass of a liquid substance affected after it boils?
When a liquid substance boils, it undergoes a phase change from liquid to gas. During this process, the mass of the substance remains unchanged, as the molecules transition from the liquid phase to the gas phase without any loss or gain of matter. However, if the gas escapes the container, the mass of the remaining liquid will decrease. Thus, the mass of the entire system depends on whether the gas is retained or allowed to escape.
What is the formula for calculating heat capacity and how is it used in determining the amount of heat absorbed or released by a substance?
The formula for calculating heat capacity is Q mcT, where Q represents the amount of heat absorbed or released, m is the mass of the substance, c is the specific heat capacity of the substance, and T is the change in temperature. This formula is used to determine the amount of heat absorbed or released by a substance by taking into account its mass, specific heat capacity, and the change in temperature it undergoes.
When a gas is heated its mass?
The TOTAL mass of the sample stays the same, but keep in mind that you can only measure it accurately if you can keep the sample confined, which can be difficult when changing a liquid to a gas. When heating a gas, it usually expands (or increases pressure in a rigid container).
