From the first law of thermodynamics, we use the equation expressed as:
ΔH = Q + W
where Q is the heat absorbed of the system and W is the work done.
We calculate as follows:
ΔH = Q + W
ΔH = 829 J + 690 J = 1519 J
Hope this answers the question. Have a nice day.
A boiling pot of water (the water travels in a current throughout the pot), a hot air balloon (hot air rises, making the balloon rise) , and cup of a steaming, hot liquid (hot air rises, creating steam) are all situations where convection occurs.

Barometer duhhhh what’s else a ruler
<span>Before we can use parallax to measure the distance to a nearby star, we first need to know the Earth-Sun distance.
Not before we find out what the distance between our planet and the Sun is can we use the parallax to measure the distance to a nearby star.
