Answer: The new pressure will be 1.42 atm
Explanation:
To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:
Putting values in above equation, we get:
Hence, the new pressure will be 1.42 atm
Answer:
Explanation:
The balanced reaction would be:
H3PO4+3KOH==>K3PO4+3H2O
Mechanical waves can help in the treatment of cancer due to heat generated by the high frequency waves.
<h3>What is mechanical wave?</h3>
A mechanical wave is a wave that requires material medium for its propagation, example include;
- water waves,
- sound waves, and
- seismic waves.
<h3> Mechanical waves in treatment of cancers</h3>
Sound wave in example of mechanical wave because it requires material medium for its propagation.
High-frequency sound waves (HIFU) is used in the treatment of cancer because the strong beam generates heat which is directed to a specific part of a cancer.
The heat generated destroys the cancer cells.
Thus, mechanical waves can help in the treatment of cancer due to heat generated by the high frequency waves.

For a candle to burn, it requires a spark, which provides the activation energy for the oxidation reaction of the hydrocarbon making the candle.
It also requires oxygen to facilitate the oxidation of the hydrocarbon.
Therefore the two main requirements of combustion of a candle are oxygen and a spark (or an initial flame)
