How much water can i put in 500ml plastic container and microwave till hot?

[orabrush]

I want to keep something warm for a few hours and I am going to use a container of plastic hot water.

First you'd have to define the word "hot", then determine whether the plastic will endure such heat.

Why not microwave in a glass container, then transfer the water into the plastic one.

Use the kettle to boil the water and then pour it into the bottle.  I hope it doesn't melt so place it in the sink first just in case.

Use at least 500ml of water and anything left over you can use to make a cup of tea.

I don't think there'll beany left over if you use 500ml of water from a 500ml container  😄

Hehehe.  Might pay to add a little extra and I had it the wrong way around.  Water expands when it freezes, not when it boils.... I think 

[*mrgrizz*]

you can put 184 litres into the container.................i don't think it will stay there though

Be careful to leave room for the steam too!

[icyfroth]

around half a litre, I'd say....

Water expands when it freezes, but it also expands as it gets hot; that is why boiler would explode if it did not have safety valves

Is the plastic container microwaveable and able to stand very hot/boiling water in it?

Where did the 'bottle' come from?

Would it better to have a metal oven dish in the regular oven, with the hot water in it, to put this thing in to keep it warm?
