Answer:
According to Boyle's law pressure of a particular amount of gas is inversely proportional to the volume of the gas. So, when we increase the pressure of the gas the volume of the gas decrease and the gas start to condense.

Answer: Scientist shoot a whole bunch of neutrons at uranium-235 atoms. When one neutron hits the nucleus the uranium becomes U-236. When it becomes 236, the uranium atoms wants to spilt apart. After it splits it gives off three neutrons and a lot of energy.
Explanation:
0.379 J · g⁻¹ · °C⁻¹.
<h3>Explanation</h3>
Energy change Q = c · m · ΔT.
Temperature change ΔT = Final Temperature - Initial Temperature.
The final temperature of both brass and water is 32.0 °C. However, the two differ in initial temperature.
Initial temperature
- Brass: 95.0 °C;
- Water: 25.0 °C.
How much energy did water gain in this process?
- Heat capacity c: 4.18 J · g⁻¹ · °C⁻¹;
- Mass of water m: 335 g;
- Temperature change ΔT: 32.0 - 25.0 = 7.0 °C.
.
How much energy did brass lose in this process?
The brass cylinder is cooled in a calorimeter. The calorimeter traps heat inside, such that water absorbs all the heat lost from the brass.
.
What's the heat capacity of brass?
- Heat capacity of brass is to be found;
- Mass of the cylinder: 410 g;
- Temperature change: 95.0 - 32.0 = 63.0 °C.

Answer:
21.88mL is the volume of base required for the titration.
Explanation:
For an acid-base titration trying to find the concentration of an acid, you must add a known quantity of the acid and titrate it with an standarized base.
If you know the moles of base you add to the acid solution, these moles are equal to moles of acid.
In the buret of the titration, initial volume is 1.94mL and final volume is 23.82mL. The volume you are adding is the difference between initial and final volume, that is:
23.82mL - 1.94mL
<h3>21.88mL is the volume of base required for the titration.</h3>
