The thermal energy of the water. Because the water is waaay above Absolute Zero (0K, or -273,15 C) it holds thermal energy or aka the temperature of the water. If the temperature of the water is higher than the one in the thermometer, the heat will 'flow' into the liquid (mostly mercury or modern, it is ethanol), causing the liquid to rise since it's volume increases. The same when te water has lower temperature. The thermal energy of the thermometer will 'flow' in the water and the volume shrinks, causing the liquid to go down. Simple thermodynamics.

Firlakuza [10]

Answer: Yes.

Explanation:

Assuming Earth and Moon are isolated is space, it is possible to have a point where Earth and Moon will pull at an object with equal force.

That point will be closer to the Moon than the Earth because Moon's gravitational field strength is weaker than Earth's gravitational field strength.

Lori wants to send a box of oranges to a friend by mail. The box of oranges cannot exceed a mass of 10.222 Kg. If each orange ha
Sergeu [11.5K]

Explanation:

Given that,

The box of oranges cannot exceed a mass of 10.222 Kg if we are sending to a friend by mail.

The mass of each orange is 198 g

We know that,

1 kg = 1000 g

10.222 kg = 10.222×1000 g

Let there are n number of oranges. So,

n=\dfrac{10.222\times 1000\ g}{198\ g}\\\\n=51.92\approx 52\ \text{oranges}

It means she can send 52 oranges and it is maximum quantity.
