# Fluid mechanics Volume change with temp change

• dev12345
In summary, as temperature increases, the volume of fluids also increases due to the increase in molecular movement. This relationship is known as Charles' Law and applies to gases at a constant pressure. The volume change with temperature varies in different types of fluids, with gases being highly affected, liquids having a small change, and solids having a minimal change. Temperature can also affect the density of a fluid, with an increase in temperature resulting in a decrease in density. The volume change with temperature also plays a significant role in the behavior of fluids, affecting properties such as viscosity, surface tension, and thermal expansion, which have important implications in fields such as engineering and meteorology.

1. A 45 US gallon drum full of water is stored at 4oC. The water temperature is slowly raised to 50oC. What is the change in volume of water over this temperature range as an absolute amount (in Litres) and as a % of the total?

dev12345: You must list relevant equations yourself, and show your work; and then someone might check your math.

## 1. How does temperature affect the volume of fluids?

As temperature increases, the volume of a fluid also increases. This is due to the fact that as temperature rises, the molecules in the fluid gain more energy and move around more, taking up more space.

## 2. Is there a specific relationship between temperature and volume in fluids?

Yes, there is a direct relationship between temperature and volume in fluids. This relationship is known as Charles' Law, which states that the volume of a gas at a constant pressure is directly proportional to its absolute temperature.

## 3. How does the volume change with temperature in different types of fluids?

The volume change with temperature varies in different types of fluids. In gases, the volume is highly affected by temperature, whereas in liquids, the change in volume is relatively small. Solids typically have a very small volume change with temperature.

## 4. Can temperature also affect the density of a fluid?

Yes, temperature can also affect the density of a fluid. As temperature increases, the density of a fluid decreases. This is because the molecules in the fluid spread out and take up more space, resulting in a decrease in density.

## 5. How does the volume change with temperature affect the behavior of fluids?

The volume change with temperature plays a significant role in the behavior of fluids. It can affect properties such as viscosity, surface tension, and thermal expansion. These changes in behavior can have important implications in various fields, such as engineering and meteorology.
