How does temperature affect the state of a material?
Temperature has a direct effect on whether a substance exists as a solid, liquid or gas. Generally, increasing the temperature turns solids into liquids and liquids into gases; reducing it turns gases into liquids and liquids into solids.
What does temperature of an object tell us?
The temperature of an object, usually measured in degrees-Fahrenheit or degrees-Celsius, tells us how much heat, or energy, the object has. If there isnt any heat being transferred between two objects, those objects are the same temperature.
What happens when the temperature of an object decreases?
When we decrease the temperature, less heat energy is supplied to the atoms, and so their average kinetic energy decreases. When they enter a phase transition, such as freezing from a liquid to a solid, the temperature is not decreasing or increasing, and stays constant.
How does temperature of matter affect the mass of an object?
When you heat the temperature the atoms in the object move faster. So that’s how the mass of an object changes. We didn’t have any problems! How does temperature of matter affect the mass of an object?
How does temperature affect the density of a substance?
As temperature increases, the density of liquids and gases decreases; as temperature decreases, the density increases. Density is the amount of mass per unit of volume. As temperature decreases, the molecules move more slowly, so they collide less and take up less space and the substance’s density increases.
How does temperature affect the activity of an enzyme?
When the temperature increases, the kinetic energy of the substrate and enzyme molecules also increase which affects the reaction rate. With rise in temperature, the number of collisions per unit time of tannase and its substrate, tannic acid increases, resulting in a higher activity.
How does temperature and salinity affect the density of water?
The warmer the water, the more space it takes up, and the lower its density. When comparing two samples of water with the same salinity, or mass, the water sample with the higher temperature will have a greater volume, and it will therefore be less dense.
