Answer:
B
. Knowing the climate makes it easy to predict the weather.
C
. If it is cold today, you almost certainly live in a cold climate.
D
. Weather can change quickly, but climate changes slowly.
Explanation:
If we know the climate of a particular region we can predict the weather of the next day or week of that region because climate is remain the same of a specific region. If the weather is cold it means that you live in a cold climate, similarly, if the weather is warm it means the climate of that region is warm and hot. Weather can change and has high variations whereas climate is the average atmospheric conditions of a region for a long period of time.
Answer:
Physical Change:
- Boiling water
- Breaking a pencil
- Water evaporating
- Denting a car door in an accident
- Tearing paper
- Ice melting
- dissolving
Chemical Change:
- Something rusting
- photosynthesis
- metabolism/digestion
- Nuclear power [atoms are arranged differently]
- Smashing paper with two metal balls, burns paper
- Electricity in water, breaks H2O into H2 and O2
-----
physical change is when there is only physical change occurring--and it can typically be undone easily,
whereas chemical change is when there is chemical change--which changes the chemical properties of something, which cannot be undone simply.
hope this helps!!
