The way to see water's temperature

Here's how to tell whether a glass contains(容納)hot water or cold water-without ever touching it!

You'll need

2 drinking glasses that are exactly alike

Ice cubes(塊)

Adult helper

Bathtub(浴缸)or shower

Pencil and paper

1.Fill one glass with cold tap water and cool it with ice cubes. Don't use a lot of ice; just cool it a little.

2.Fill the other glass with very hot water.

3.Pour both glasses out into the tub at the same tirme and speed.

Repeat this process(過程)a fewtimes,and watch closely each time.

4.Ask your helper to fill the glasses again and not tell you which is which.

When you see the water splash in the tub.guess which one is the hot water.

5. Repeat several times. Keep score on your paper.

You should be able to guess correctly more than half the time.

Cold water is more dense(稠密的)than hot water.so a cup of cold water is just a little bit heavier than a cup of hot water.

When you pour hot water onto a hard surfaceit splashes(濺起)around more than the cold water because it's less dense.

【題目】

On April 2, we said goodbye to Tiangong I, China’s first space lab. According to the China Manned Space Agency (中國載人航天), Tiangong I re-entered the Earth’s atmosphere (大氣層) and some of its debris (碎片) fell into the South Pacific Ocean.

There are many spacecraft (宇宙飛船) that are still in orbit

(軌道) above the Earth. After finishing their trips, they will all re-enter the Earth’s atmosphere like Tiangong I.

There are two types of re-entries: controlled re-entry and uncontrolled re-entry.

Some satellites and manned spacecraft come back to the Earth in a controlled re-entry. Experts calculate (計(jì)算) the path of the falling spacecraft and its speed. Thy can guide the spacecraft to fall in a chosen area.

Some spacecraft may have problems while in space after a certain amount of time. These spacecraft come back in an uncontrolled re-entry. It is hard to tell when and where these spacecraft will fall until the last few hours. The US space station Skylab came back partially uncontrolled in 1979. Parts of the station fell in western Australia, but no one was hurt.

During re-entry, most of the spacecraft will burn up while passing through the Earth’s atmosphere. Only a small amount of the debris will reach the ground. The debris typically ends up falling into the ocean, China Daily reported.

A. fell into the South Pacific Ocean B. fell in western Australia
