Which two forms of heat transfer or work together to heat water in a plastic bottle?
convention and conduction
Why do you think the thermos bottle contains a vacuum or space from which the air has been removed?
it prevents conduction and convection the 2 main causes of heat transfer
How does a vacuum bottle keep food hot or cold?
The main idea is to reduce the heat transfer out of the vacuum bottle, or into it. A vacuum greatly reduces the transfer of heat by conduction and convection, while the mirror reduces heat transfer by radiation.
Does a hot water bottle use conduction?
Yes
How does a thermos bottle work?
It uses as vacuum to insulate the inside from the outside. The vacuum reduces the different ways heat can be dissipated; mainly conduction and convection. Very importantly, a Thermos bottle, scientifically called a "Dewar's flask," incorporates a radiant barrier that directs radiant heat back into the hot liquid in the bottle. You can usually see the radiant barrier when the flask incorporates a glass liner, the barrier is the shiny material across the vacuum from the glass. The three ways heat can move are conduction, (through a solid), convection, (through a gas or liquid), and radiation, (through a gas or vacuum). The Dewar's flask addresses all three of the means of heat transfer, that is why it is so efficient. that is true trust me

What are some of the benefits to purchasing a baby bottle warmer?
A baby bottle warmer is a modern alternative to the traditional method of warming a baby's milk. Traditionally this would involve putting the baby's bottle in a jug of hot water. The main advantage in using a baby bottle warmer is that it is portable and so is ideal when travelling or away from home.

What does silver layer of an insulated bottle does this to radiated heat?

How does a vacuum flask keep its energy?
1. Silvered interior reflects any heat which may transfer though radiation 2. Moderately hard vacuum almost eliminates transfer by conduction (& convection though this would be modest anyway) 3. Vacuum bottle is only supported by a few small rubber pads - again limiting conduction 4. Cap designed with air gaps to reduce conduction: plastic/air/plastic/air/plastic 5. Most flasks have an outer of plastic which is a reasonable insulator against conduction heat loss. The vacuum itself is the most significant design point.
Why does the water vapour surround the cold water bottle?
The water in the bottle is much colder than the air surrounding it, so the bottle cools the air immediately surrounding it through conduction. This causes the air to cool to its dew point, whereupon some of the moisture in the air will condense onto the bottle.
How do you heat a bottle of water in the sun?
Wrap the bottle in a single layer of black cloth or plastic. The sun's heat will be absorbed by the black cloth and heat the water in the bottle. This is similar to warming water using solar panels on the roof.
What direction does energy flow to the cool air inside the bottle?
There's not enough information to properly answer this question, but I would assume, if the air is inside a bottle of some sort, we're thinking of convection.
