Explanation:
This process is called photosynthesis and is performed by all plants, algae, and even some microorganisms. To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis.
The first choice is correct
Answer:
There is no friction because of the mass.
Explanation:
The bigger box ran out of force to move so it hit the smaller box. (im in 7th grade and have the answer key)
Answer:
619.2 K
Explanation:
We can solve this problem by using Charle's Law, which states that:
"For a fixed mass of an ideal gas kept at constant pressure, the volume of the gas is directly proportional to its absolute temperature"
Mathematically:
![V\propto T](https://tex.z-dn.net/?f=V%5Cpropto%20T)
where
V is the volume of the gas
T is the absolute temperature
The equation can be rewritten as follows for a gas that undergoes a transformation at constant pressure:
![\frac{V_1}{T_1}=\frac{V_2}{T_2}](https://tex.z-dn.net/?f=%5Cfrac%7BV_1%7D%7BT_1%7D%3D%5Cfrac%7BV_2%7D%7BT_2%7D)
where in this problem:
is the initial volume of the gas
is the initial temperature
is the final volume of the gas
Solving for T2, we find the final temperature:
![T_2=\frac{V_2 T_1}{V_1}=\frac{(2.28)(288)}{0.736}=892.2 K](https://tex.z-dn.net/?f=T_2%3D%5Cfrac%7BV_2%20T_1%7D%7BV_1%7D%3D%5Cfrac%7B%282.28%29%28288%29%7D%7B0.736%7D%3D892.2%20K)
Converting into Celsius degrees,
![T_2=892.2-273=619.2 K](https://tex.z-dn.net/?f=T_2%3D892.2-273%3D619.2%20K)
