Answer:

Water absorbs 84cal.

Explanation:

The given information about water is:

- mass of water (m): 12g

- change in temperature (ΔT): 7°C

With the given information, and the specific heat of water (c=1cal/g.°C), we can calculate the aeat that water absorbs, using the heat formula:

\begin{gathered} Q=m*c*\Delta T \\ Q=12g*1\frac{cal}{g*\degree C}*7\degree C \\ Q=84cal \end{gathered}

So, water absorbs 84cal.

Describe how you would use a calorimeter to determine the specific heat capacity of a metal
vovikov84 [41]
<span>My only guess is obtain a metal and heat it in a boiling water bath (of known temperature) this will be your initial temperature. Now obtain a calorimeter cup with water of known temperature as well. Place the metal into the calorimeter cup and record the temperature after 5 minutes. You now have delta T, mass of the metal, and Q. Solve for C.

Hope this helps xox :)</span>

How would a fast-flowing river be most likely to move sand-sized particles of sediment?
Nitella [24]
A fast-flowing river would most likely be to move the skaters glide around the rink b<span>y lifting it up and carrying it downstream. In a fast-flowing river, the pressure is strong, which makes it easier for sand-sized particles of sediments to be carried or transferred. Hope this answer helps.</span>
