Why it incorrect to say that insulation keep out the cold?
Because in science, cold doesn't exist. You can't make cold, you can only remove heat. But in human language we've made words to describe the absences too. Dark is the absence of light. Cold is the absence of heat. Vacuum is the absence of all material. So insulation can't keep the cold out, since the cold doesn't exist. What you can do though is keep the heat in. Heat is a real thing. You can make heat.
How is heat being transfered when you place your finger in the cold beaker why?
If the beaker has a cold water, or something else cold, in it than the heat that is in our finger will run out of you finger into the cold water. This leaves your finger 'empty' of heat, giving you the sensation of being cold. You need to remember that only heat moves. When you are cold you wear a jumper that keeps the heat in your body, not keep the cool out.
Why newspaper wrapping keep thing hots and cold things cold?
Paper is an insulator- it does not transmit heat well, so it keeps heat in (or out) of things.
How does cloth keep things hot and cold?
Cloth is a bad conductors/good insulator of heat. Bad conductors keep things warm or cold, so the answer is, because cloth is a bad conductor of heat!
Will black blinds keep heat in a room?

Can rock keep something cold without ice?
it can keep it cold because the rock can keep the coldness and take the heat away=p<3
What keep the cold water cold?
Lack of heat energy in the surrounding area to warm it up.
Why is tin not a good insulator?
This is because tin is an excellent conductor of heat, meaning, heat passes right through it. So if you are trying to keep something hot from getting cold, the heat will escape and if you are trying to keep something cold from melting then heat will get in and melt it.
Is it more energy efficient to do a double paned window replacement?
Yes, double paned windows will keep out the cold and keep in the heat. In the summer, they will keep in the cold and keep the heat out. These are more expensive than normal windows but worth it with the energy savings.
