And what is the dependent variable for this experiment
Answer:
Independent variable - temperature
Dependent variable - tablet dissolving affect.
Explanation:
The Independent variable in an experiment is characterized as the variable in the experiment that is not affected by a change in any other variable or factor. It could be changed or manipulated to observe its impact on the dependent variable. While a dependent variable is the one that is affected by any change in the independent variable.
In the given experiment, the 'temperature' is the independent variable as it can be controlled or manipulated to observe the effect in the dependent variable. The 'tablet dissolving effect' would be the dependent variable as it is directly affected by any change in the independent variable(the higher the temperature, the easier the tablet gets dissolved).
Answer:
Seatbelts stop you
Explanation:
Any passengers in the car will also be decelerated to rest if they are strapped to the car by seat belts.
Answer:
When a physical change occurs, the mass of the substance is conserved. This means that the total mass of the substance remains the same from beginning to end. The physical properties of the substance, such as size and shape, may change, but the amount of matter in the substance does not change.
Explanation:
Explanation:
When there is no change in chemical composition of a substance then it is known as physical change.
When we say that mass is conserved during a physical change then it means that total mass of the substance or object will remain the same from beginning till the end.
For example, a metal box of mass 20 grams is beaten with hammer. Its shape will change which is a physical change and after beaten with the hammer its mass still remains 20 grams.
