Assume the pressure inside and outside the balloon is equal at 1 atmosphere. For ease of calculation, the volume and mass of the balloon and string are assumed to be zero. Pressure on a Balloon In … more
Drinks in a straw aren’t pulled, they’re pushed. When we say ‘straw,’ most people picture liquid being sucked upward. But scientifically, that’s not what happens. The liquid doesn’t rise because of suction; it rises because the … more
Pressure is defined as the force applied per unit area. When the same force is applied to two different surfaces, the pressure depends on the size of the area: the larger the area, the smaller the … more
Conduction The ‘conduction’ of heat is how heat is transferred by moving particles that make up an object to neighboring particles. Heat can be transferred even if the particles do not move, mainly by vibration or … more
Convection in the room There are three ways to transfer the heat: conduction, convection, and radiation. Convection is the method by which heat is transferred by the direct movement of particles that make up a liquid … more
Particle movement according to temperature The matter around us is made up of tiny particles constantly moving. The particles move more actively as the temperature increases. Water particles move more actively in hot water than cold … more
Kinetic theory model Gas particles are constantly moving in all directions. However, we cannot observe these gases because they are very small. The “Kinetic theory model” can replace these invisible gas particles with beads and make … more
Boiling point and properties of substances All water boils at 100°C when heated, even if it has a different mass. In this way, the same kind of substance has the same boiling point regardless of quantity. … more
* By adjusting the temperature of the thermometer, you can observe the state of the water corresponding to the temperature. * Depending on the temperature of the water, some water molecules may evaporate. State of matter … more
Vacuum Jar A vacuum jar(or vacuum sealer, vacuum container) is a container that can remove air using a pump. Originally, vacuum jars were made as kitchen utensils to help meat soak in seasoning. Now, they are … more
