Sorry the format sucks, I’m on mobile.
So, I have a 4 month old. On occasion I warm formula that has been in the fridge in the microwave. 20 seconds, All it needs. Yes, I shake it and test it on my arm everytime to make sure it is just right and i barely do this as i have a baby brezza. Don’t come at me. Lol.
Now today my 9 year old who is dealing with sensitive teeth asked me is I could warm her pear juice for her. Sure, no prob. The pear juice took 40 seconds just to reach room temperature. Why is this? Is it the sugars? I don’t know why this just occured to me and is bothering me but here we are.
In: Chemistry
This is to do with what’s called heat capacity.
Heat capacity is an extensive property that determine how much energy is required to increase its temperature.
Heat capacity is determined by 3 factors: the change in temperature, the mass of what’s being heated and finally substance and phase of the substance.
The main reason why something will heat quicker in an example of water or alcohol is density difference between the two liquids but there are many factors such as initial viscosity, other compounds in the liquid etc that can reduce or increase a liquid heat capacity
Unfortunately there isn’t an easy way to expand on this from my knowledge as it involves lots of complex maths and I’m not good at explaining maths haha
