What is pressure ? Write an experiment to show that liquids exert pressure sideways
Answers
Answer:
Pressure is defined as special force excreated from an object. The force applied is perpendicular to the surface of objects per unit area. The basic formula of pressure is F/A ( Force per unit area).

Baloon air pressure Expiriment
¡. Use heat to change the air pressure inside the bottle causing a Baloon set on top of the bottle to squeeze into it. When you first set the water valoon on top of the jar, the air pressure outside the jar and the air pressure inside the jar are the same. As the fire burns the air, heated by the fire

Explanation:
To see if liquid exerts pressure side ways.... 2. The edge of a blunt knife is broader than a sharp knife. thiis exerts less pressure on the object than a sharp knife
Now make holes in all the directions. Now fill with water. The water comes out of the bottle in all the direction. This shows that liquids exert pressure in all direction.The pressure a fluid exerts on an object in the fluid is applied in all directions. That is because the particles that make up the fluid can move in any direction. These particles exert forces as they bump into objects in the fluid.The card sticks to the glass. This is due to air pressure. The air outside exerts an upward pressure on the index card. This air pressure is more than the weight of the water in the glass.
