Answer:
New volume is 14.35 mL
Explanation:
When a system of a gas keeps on constant its temperature and number of moles, the pressure is modified indirectly proportional to the volume:
Pressure increased → Volume decreased
Pressure decreased → Volume increased.
The relation you have to apply is: P₁ . V₁ = P₂. V₂
1.23 atm . 35 mL = 3 atm . V₂
(1.23 atm . 35 mL / 3 atm) = V₂
V₂ = 14.35 mL
The answer to this question is C, I hope this helps you!
The correct answer is 5819.04 J
The energy (q) required to elevate an object of mass (m) and specific heat capacity (c) by a temperature (T) is given by q = mcΔT.
Here, m is 72 g, c is 0.449 J/Kg °C, ΔT = 260 - 80 = 180 °C
Now, putting the values we get,
q = 72 × 0.449 × 180
q = 5819.04 J of energy is absorbed by the skillet.
Answer:
in this situation I would a little bold
Explanation:
first I don't know what extinguisher I would use pretty much any that helps with fires. I'll back people up, take the hood and put it on the small fire that way it will light out more and if I open the hood and there still a little fire I would use the extinguisher and no one gets hurt :)
