True or False 1. When an object is completely immersed in a fluid, the buoyant force depends on the object's volume. 2. When an object is completely immersed in a fluid, the buoyant force depends on the object's density. 3. A tornado surrounds a car parked in an open field. If the windows of the car shatter, the glass shards will be equally likely to land both inside and outside the car. 4. When blood flows quickly through a narrowing of an artery, the artery can be squeezed shut by the surrounding body tissue. 5. The equation of continuity (A1v1 = A2v2) is based on the idea that the rate at which mass enters a pipe equals the rate as which mass leaves the pipe. 6. Two helium balloons are held near each other by vertical strings. If you blow directly in between them, the balloons will move toward each other.
Kinetic Theory of Gas
The Kinetic Theory of gases is a classical model of gases, according to which gases are composed of molecules/particles that are in random motion. While undergoing this random motion, kinetic energy in molecules can assume random velocity across all directions. It also says that the constituent particles/molecules undergo elastic collision, which means that the total kinetic energy remains constant before and after the collision. The average kinetic energy of the particles also determines the pressure of the gas.
P-V Diagram
A P-V diagram is a very important tool of the branch of physics known as thermodynamics, which is used to analyze the working and hence the efficiency of thermodynamic engines. As the name suggests, it is used to measure the changes in pressure (P) and volume (V) corresponding to the thermodynamic system under study. The P-V diagram is used as an indicator diagram to control the given thermodynamic system.
