Answer:
answer is 2.04*10^4 kPa
Explanation:
Dalton's Law of Partial Pressures.
it is because that when the volume and the temperature of a gaseous mixture are kept constant, the total pressure of the mixture is equal to the sum of the partial pressures of its gaseous components .
B because you can feel the current
ANSWER: D) distributaries
EXPLANATION: When a deposition causes the main channel of a stream to divide into several smaller channel it is called a distributary. They are a common feature of river deltas and is also known as river bifurcation. A distributary generally occurs near a lake or ocean and can also occur near a confluence of large stream. This is popularly also known as arm or channel.
Answer:
Lithium has a melting point of 180.54 C, a boiling point of 1342 C, a specific gravity of 0.534 20 C
Explanation:
Answer:
605.4 J
Explanation:
When a certain substance absorbs a certain amount of energy, its temperature increases according to the equation:
where
Q is the heat absorbed
m is the mass of the substance
C is the specific heat capacity of the substance
is the change in temperature
In this problem, we have:
m = 15.5 g is the mass of the piece of aluminium
C = 0.902 J/g⁰C is the specific heat of the aluminium
is the change in temperature of the aluminium (in fact, at thermal equilibrium, the block of aluminium reaches the same final temperature as the coffee)
Therefore, the energy absorbed is
