Answer:
4510 J
Explanation:
To calculate the energy of the water, you need to use the following equation:
Q = mcΔT
In this equation,
-----> Q = energy/heat (J)
-----> m = mass (g)
-----> c = specific heat capacity (J/g°C)
-----> ΔT = change in temperature (°C)
First, you need to determine the mass of the water. To do this, you need to multiply the given volume by the density of water (1.00 g/mL).
100.0 mL H₂O 1.00 g
------------------------ x ------------ = 100.0 g H₂O
1 mL
Now, you can plug the given values into the equation and solve for "Q" (Q =
). The final answer should have 3 significant figures to match the given values with the lowest number of sig figs.
Q = ? J c = 4.18 J/g°C
m = 100.0 g ΔT = 32.0 °C - 21.2 °C = 10.8 °C
Q = mcΔT
Q = (100.0 g)(4.18 J/g°C)(10.8 °C)
Q = 4510 J
Answer:
This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs. ... Carbon dioxide is the waste product of cellular respiration that you breathe out each time you breathe.
