How do I work out the rate of heat transfer between different states of matter? Say for example I wanted to calculate how long it takes for a freezer at -15 degrees to freeze 30g of water in a cup at 10 degrees, what equations would I need to use?(adsbygoogle = window.adsbygoogle || []).push({});

I've already worked out that 11,274 joules needs to be extracted from the water.
