temperature measures heat - the unit is Celsius - and it is measured with a thermometer.
length is measuring how long, tall, or wide something is - the base unit it metres - and it is measured with a ruler or a metre stick
volume is measuring the quantity of a three dimensional space - the unit is cubic centimetre - you find volume by taking the measurements with a ruler
mass is measuring how much space something takes up/ weight - unit is the gram - you use a scale
Magnetic fields can go through some materials (like cardboard). Electric fields can also do that. Electromagnetic waves can do that. It’s not at all unusual because magnetic fields are not made up of particles so they can go through materials.
Elements and compounds
Explanation:
- All pure substances are distinct substances.
- All their parts are the same throughout i.e they are homogeneous.
- They have a definite composition.
- They cannot be easily separated or broken down into simpler substances by physical means.
- They have a unique set of physical properties.
Elements are distinct substances that cannot be split up into simpler ones.
Compounds are substances composed of two or more kinds of atoms joined together in a definite grouping.

Answer:
The final temperature is T2= 5.35°C
Explanation:
Apply the Gay-lussacs's law we have
P1, initial pressure= 5.00 x 10^6 Pa
T1, initiation temperature= 25.°C
P2, final pressure= 1.07 x 10^6 Pa
T2, final temperature= ?
Cross multiplying and making T2 subject of formula we have
T2= 5.35°C
Answer:
Explanation:
A body has acceleration when there is a change in the velocity vector, either in magnitude or direction. In this case we only have a change in magnitude. The average acceleration represents the speed variation that takes place in a given time interval.
