Answer:
4202.1 K
Explanation:
From;
PV=nRT
P= pressure of the gas = 18.5 bar
V = volume of the gas = 115L
n= number of moles of the gas = 6.1 mole
T= temperature of the gas = ?
R = gas constant = 0.083 L⋅bar⋅K−1⋅mol−1
T = PV/nR
T = 18.5 * 115/6.1 * 0.083
T = 2127.5/0.5063
T= 4202.1 K
<span> An object with a high specific heat would change temperature more slowly than one with low specific heat. Water, for example has a very high specific heat so it requires a lot of energy to heat it up. It also takes a while for water to cool down because it holds that heat for a long time. <3</span>
pretty positive the answer is 1
A.) The reaction is Exothermic
Answer : First, he should measure how long it takes for the liquid to become clear if X and Y are mixed together. Then, he should measure how long it takes if he also adds substance A to X and Y. He will find out if substance A is a catalyst
Explanation : Measuring the time taken for the liquid to become clear when X and Y were mixed together will give an assumption about the reaction time and the rate of reaction.
Then same measurement should be done when the substance A is added to the liquid of X and Y mixture. If there is a fast reaction that occurs when A is added to the reaction mixture then it can be concluded that A acts as an catalyst for mixing X with Y. Also, by comparing the reaction rates of both the reaction it can be easily concluded that A was a catalyst or not.
