A student would like to determine how heating a liquid changes its volume. The student hypothesizes that the liquid will increase in volume. The following list shows the steps taken by the student in order to test the hypothesis.

Select the liquid to test.

Place the liquid in a sealed container.

Use a Bunsen burner to heat the liquid by 10°C.

Measure the volume of the liquid.

Record the results.

What is wrong with how the student conducted the investigation?

a The volume of the liquid should be measured before it is heated.

b The hypothesis was not valid because it is impossible for liquids to change in volume.

c The student should have increased the temperature of the liquid by more than 10ºC.

d The length of time it took for the liquid to be heated should be measured.

The answer is A i.e The volume of the liquid should be measured before it is heated. I think this is surely right!!

Match the givin changes in the ecosystem to their causes
poizon [28]

Answer:

The correct answers are:

1. Greenhouse gases: Earth's heat is kept from going away.

Greenhouse gases, particularly CO2 and methane, have properties that allow them to trap heat in the atmosphere. This means that the more of these gases there are in the air, it will be hotter on Earth.

2. Chemicals released into the river—unfit for human consumption.

The chemicals released into rivers pollute the water, making it unfit for human consumption. There are only a few places in the world where there is enough freshwater to go around, so the fact that so many rivers have been poisoned is very worrying.

3. Excessive agricultural land use—forest fragmentation.

People cut down the trees so that there is more land that can be used for farming, As a result of this process, forests are being destroyed to the point of total devastation, and it is likely that this percentage will rise in the coming years as things continue.
