Most likely, exothermic processes are what cause the light that fireflies emit. because fuel and oxygen undergo a chemical process that produces carbon dioxide and water.
In thermochemistry, an exothermic process is one "for which the overall standard enthalpy change H is negative." Exothermic processes typically result in heat. A reaction for which the overall standard Gibbs energy change G is negative is what the term "reaction" according to the IUPAC means.
The exergonic response and the phrase are commonly mistaken. A very exothermic reaction will often accompany an exergonic reaction since "H" significantly contributes to "G." The majority of the remarkable chemical reactions presented in classrooms are exothermic and exergonic processes.
On the other hand, an endothermic reaction typically produces heat and is brought on by a rise in the entropy of the system.

Answer: Heat energy is the transfer of<u> thermal energy.</u>
Explanation:
Answer:
The correct answer is 0.75 atm
Explanation:
We have carbon monoxide gas (CO) at the following conditions:
T= 30ºC = 303 K
V= 20.0 L
m = 17 g
The molecular weight of CO (MM CO) is the following:
MM CO= molar mass of C + molar mass of O = 12 g/mol + 16 g/mol = 28 g/mol
We calculate the number of moles (n) as follows:
n= m/MM CO = 17 g/28 g/mol = 0.61 mol
Finally we use the ideal gases equation to calculate the pressure (P):
P x V = n x R x T
P = (n x R x T)/V
P= (0.61 mol x 0.082 L.atm/K.mol x 303 K)/20.0 L
P= 0.75 atm
