What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg).

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity (W = m * g).

Front

What is the approximate weight of a 20 kg object on Earth?

Back

The weight is approximately 200 N (Newtons), using 10 m/s² for gravitational acceleration.

Front

What is a heterogeneous mixture?

Back

A heterogeneous mixture is a combination of substances that are not uniformly distributed, meaning the different components can be seen and separated.

Front

What is a homogeneous mixture?

Back

A homogeneous mixture is a mixture in which the composition is uniform throughout, and the different components are not distinguishable.

Front

What is a compound?

Back

A compound is a substance formed when two or more elements chemically bond together in a fixed ratio.

Front

What is the chemical formula for sodium chloride?

Back

The chemical formula for sodium chloride is NaCl.

Front

What is the symbol for copper?

Back

The symbol for copper is Cu.

Front

What is the process of heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another, typically occurring through conduction, convection, or radiation.

Front

What is the specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of one kilogram of a substance by one degree Celsius.
