Why do some liquids take longer to heat up than others?

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.

More stuff thats dissolved in water, the higher the temperature that it will boil. Imagine the particles in water getting in the way of the water molecules to make it harder for them to escape as gas

It doesnt matter whats dissolved in it, what matters is how much is dissolved.

This is called boiling point elevation

Edit: This is assuming we are talking about two liquids made up of water. If you have two different liquids then there is more to it, as explained by other comments.
