Scientific knowledge is constantly being refined and changed as scientists perform studies using the scientific method. New discoveries such as the recent discovoery of water on Mars, cause scientists to re-evaluate their previously held theories.
Microscope, magnifying glass,
The method is called the displacement method.
You place some water in the graduated cylinder and measure its volume.
Then you add your object and measure the new volume.
The difference between the two volumes is the volume of your object.
occurs in fluids
Explanation:
Convection is a mode of heat transfer that occurs in fluids.
There are three types of heat transfer:
conduction convection and radiation
- Conduction is a mode of heat transfer that involves an actual contact between the molecules of the medium. It occurs mostly in solids
- Radiation uses electromagnetic waves to transfer heat between two bodies or places. It does not require a material medium. The heat of the sun reaches us by radiation.
- Convection is a mode of heat transfer in fluids. It involves the density differences between hot and cold liquids and gases.
- Water boils by convection currents.
