This is Miss Martindale’s tricky question:
If I leave bottle of lemonade without the lid on and then re-weigh it after a couple of days will its mass have decreased since the start?? (In other words will the bottle of lemonade get lighter if I leave the lid off?)
What is your prediction? Can you explain WHY you think that?
We will find out later in the week.

i think that it will get lighter because if the sun was out it will get lighter and the lemonade will get smaller and smaller.

Why? Can you explain using science vocabulary what would be happening?

I think it will get lighter because the sun would dry it up

I think Udeshpal and Kemal are thinking of evaporation. What if the bottle was inside. Would the sun still ‘dry it up’ / evaporate the liquid?
What is in the bottle as well as a liquid? Will it leave the bottle? Does it have a mass?

If the bottle was inside then i think it will evaporate a tiny small bit but it won’t get lighter

I think it will get lighter because the sun will make all the fizz go
