Answer:
Genes mainly, however the environment as well
Explanation:
<u>Answer:</u> The new volume will be
<u>Explanation:</u>
To calculate the new volume, we use the equation given by Boyle's law. This law states that pressure is directly proportional to the volume of the gas at constant temperature.
The equation given by this law is:
(at constant temperature)
where,
are initial pressure and volume.
are final pressure and volume.
We are given:
Putting values in above equation, we get:
Hence, the new volume will be
Answer:
Sunlight. and maybe dead wood and sticks.
Explanation:
Lots of trees compete for the most sunlight. That's why if you go to a rain forest, there are different levels of ecosystems and sizes of trees.
Both beavers and otters compete for these sticks, if the beavers don't build strong enough, their home will collapse.
Answer:
The correct answer is A. Barium Chloride
Explanation:
Answer:
–48.3 KJ
Explanation:
Data obtained from the question. This includes the following:
Mass (M) = 550g
Initial temperature (T1) = 25°C
Final temperature (T2) = 4°C
Change in temperature (ΔT) = T2 – T1 = 4°C – 25°C = –21°C
Specific heat capacity (C) = 4.184J/g°C
Heat (Q) =.?
The heat transferred can be obtained as follow:
Q = MCΔT
Q = 550 x 4.184 x –21
Q = – 48325.2 J = –48.3KJ
Therefore, the heat transferred is –48.3KJ since we are cooling the water.
