You can thank me if this answer helps. The energy coal comes from energy that was stored in giant plants that lived hundreds of millions of years ago in swamp forests,even before dinosaurs!
<h2>
Heat released in this process is 3516.7 J</h2>
Explanation:
A calorimeter has a heat capacity of 1265 J/°C
Heat capacity of calorimeter = 1265 J/°C
A reaction causes the temperature of the calorimeter to change from 22.34°C to 25.12°C
Change in temperature = 25.12 - 22.34 = 2.78°C
Heat released = Heat capacity of calorimeter x Change in temperature
Heat released = 1265 x 2.78 = 3516.7 J
Heat released in this process is 3516.7 J
Answer:No
Explanation: Isolated systems are systems that exchanges no matter or energy with their surroundings. An equilibrium state of an isolated system has no natural tendency to change over time. If changes do occur in an isolated system, they continue until an equilibrium state is reached.
Answer:
D. 5m
Explanation:
fλ = c, where f is frequency, λ is wavelength and c is speed.
6λ=30
λ=30/6=5
We will put the number of trips in the first column, the miles driven in the second column and gallons of fuel used in the third column.
8 7,680 1,010
7 9,940 1,330
12 14,640 1,790
12 13,920 2,050
