heating is repeated to ensure all water molecules have evaporated
Answer:
A. All of the answer choices are correct.
Explanation:
Giant sequoia trees
<u>They are long - living and the largest living organism on the planet Earth .</u>
They are majorly found in the western slopes of the Sierra Mountains present in the California .
These tress can grow to an average height of 50 to 85 meters , with diameter measuring 6 to 8 meters .
- They are also responsible for the generation of carbon dioxide via cellular respiration .
- It is the net sink of the carbon dioxide .
- It incorporates the carbon dioxide into the biomass .
Answer: 6.3 * 10^15
Explanation:
wavelength = speed of light / frequency
so rewriting the equation gives frequency = speed of light / wavelength
so 3.0 *10^10 / 4.76 * 10^-6 = 6.3 * 10^15
<u>Answer:</u> The final temperature will be 
<u>Explanation:</u>
Calculating the heat released or absorbed for the process:
In a system, the total amount of heat released is equal to the total amount of heat absorbed.
OR
......(1)
where,
= specific heat of aluminium = 
= heat capacity of water = 
= mass of aluminium = 30. g
= mass of water = 50. g
= final temperature of the system = ?
= initial temperature of aluminium = 
= initial temperature of the water = 
Putting values in equation 1, we get:
Hence, the final temperature will be
