Hello!
a gas thermometer measure temperature by measuring the pressure of a gas inside the fixed volume container a thermometer reads a pressure of 248 torr at 0 degrees Celsius what is the temperature when the thermometer reads a pressure of 345 torr
We have the following information:
P1 (initial pressure) = 248 torr
T1 (initial temperature) = 0 ºC (in Kelvin)
TK = TºC + 273.15 → TK = 0 + 273.15 → T1 (initial temperature) = 273.15 K
P2 (final pressure) = 345 torr
T2 (final temperature) = ? (in Kelvin)
According to the Law of Charles and Gay-Lussac in the study of gases, we have an isochoric (or isovolumetric) transformation when its volume remains constant or equal, then we will have the following formula:






If you want the solution in Celsius Temperature, we have:
TC = TK - 273.15
TC = 380 - 273.15
TC = 106.85 → Temperature = 106.85 ºC

Answer is: both reactions are exothermic.
<span>In exothermic reactions, heat is released and enthalpy of reaction is less than zero (as it show second chemical reaction).
According to Le Chatelier's principle when the reaction
is <span>exothermic heat is included as a
product (as it show first chemical reaction).</span></span>
Atoms combine<span> by forming chemical bonds</span>
Explanation:
1) Thermal and Electric conductivity
2) Metallic strength
