What are the ways to increase the pressure in physical resources? 10

The pressure of the solids can reduce the area of force, such as sharpening knives.

Increase pressure, such as slapping the table hard.

Liquid pressure can increase the depth of an object in a liquid or put an object into a denser liquid.

Gas pressure can increase temperature, compress volume, or increase gas mass.

All of the above methods need to be true if all other conditions remain the same).

According to the formula p=f s, just change the relevant physical quantity. For closed liquids and gases, the volume can be compressed, the volume remains unchanged, the temperature can be raised, and the compressed volume can increase the temperature at the same time; For other liquids, the pressure is the product of the density of the liquid, the acceleration of gravity g, and the height (i.e., depth).

One or three items are sufficient; For solids, just make p=f s bigger, whatever you want. In addition, slapping the table hard does not increase the pressure stably for a long time, but only converts momentum into impulse, the formula is mv=ft, pay attention to the magnitude and direction of v.

Temperature: The higher the temperature, the stronger the movement of air molecules and the greater the pressure;

Density: The higher the density, the greater the air quality and the greater the pressure per unit volume;

Altitude: The higher the altitude, the thinner the air and the less atmospheric pressure.

1.The volume does not change, and the temperature is raised.

2.The temperature does not change, and the volume is reduced.

3.Reduce the volume and increase the temperature.

Methods for increasing and decreasing pressure.

Ways to increase the pressure:

If the stress area s remains the same, the pressure f becomes larger, and the pressure p also increases.

If the pressure f does not change, the force area s becomes smaller and the pressure p becomes larger.

Three examples of increased pressure: speed skaters with skates equipped with skates; darts thrown at the target disk; Brake firmly.

Ways to reduce pressure:

If the stress area S remains the same, the pressure f becomes smaller, and the pressure p also decreases.

If the pressure f does not change, the force area s becomes larger, and the pressure p also decreases.

Three examples of pressure reduction: Truck trucks are equipped with many wheels; Houses are built on larger foundations; The bag strap is made wider.

According to the factors that affect the pressure strength, the corresponding method can be obtained: the method of increasing the pressure Sun You: when the pressure is constant, the force area is reduced; When the stress area is constant, increasing the pressure can also increase the pressure and reduce the stress area of the disturbance state at the same time;

The method of reducing the pressure: when the pressure is constant, increase the force area; When the stress area is constant, the pressure can be reduced and the stress can be increased and the pressure can be reduced at the same time

So the answer is: decrease; Enlarge; stress area; Enlarge; Minish; Stress

When the piston is pressed down, the piston does a feast on the gas, converts the mechanical energy into the internal energy of the gas, the internal energy of the gas increases, and the temperature rises brightly.

Therefore, C

pressure, area, area pressure.

The pressure is equal to the pressure divided by the force area, which is the force per unit area, theoretically the force is unchanged, the force area decreases, and the pressure increases.

The size of the pressure is related to the size of the pressure and the size of the force area In order to increase the pressure, when the pressure is constant, the pressure can be increased by reducing the force area For example, the blade of the kitchen knife is thinned

When the force area is constant, the pressure can be increased by increasing the pressure, such as pressing the pushpin force, and the pressure can also be changed at the same time to increase the pressure by changing the size of the pressure and the force area, such as pressing the pushpin hard while making the tip of the pushpin sharp

So the answer is: decrease; Enlarge; Stressstress area;

1. The pedestal under the terracotta warriors is to increase the force area and reduce the pressure.

2. The pressure of the skis is reduced and it is convenient to walk in the snow.

3. The base of the piano is cushioned with four wooden planks to reduce the pressure.

Thank you for your adoption.

1.The train has pine trees under the tracks, and there are many stones under the pine trees.

2.Wheels (chains) of tanks

The size of the pressure is related to the size of the pressure and the size of the force area In order to increase the pressure, when the pressure is constant, the pressure can be increased by reducing the force area For example, the blade of the kitchen knife is thinned

When the force area is constant, the pressure can be increased by increasing the pressure, such as pressing the pushpin force, and the pressure can also be changed at the same time to increase the pressure by changing the size of the pressure and the force area, such as pressing the pushpin hard while making the tip of the pushpin sharp

So the answer is: decrease; Enlarge; Stressstress area;
