Answer:
Thus, the joules of heat absorbed when 70.0 grams of water is completely vaporised at its boiling point are 158,200.
Answer:
wavelength = 1.71× 10⁻⁶ m
Explanation:
Given data:
Wavelength of wave = ?
Frequency of wave = 1.75×10¹⁴ s⁻¹
Solution:
Formula:
Speed of light = wavelength × frequency
wavelength = Speed of light / frequency
Now we will put the values in formula.
wavelength = 3 × 10⁸ m/s / 1.75×10¹⁴ s⁻¹
wavelength = 1.71× 10⁻⁶ m
<span>These hydrocarbons are many and this depends on the phase diagram of the substance. In a phase diagram, the phase
can be determined by looking at a certain temperature and pressure. For this case, at a temperature of 20 degrees Celsius and at 1 atmosphere.</span>
Answer:
A covalent bond is a result of sharing electrons between two atoms. The main difference between electrovalent and covalent bond is that electrovalent bond is formed when two atoms are in an electrostatic attraction whereas covalent bond is formed when two atoms share their electrons with each other.
<h3><u>Answer;</u></h3>
Surface fire
<h3><u>Explanation;</u></h3>
- <u>Surface fires are type of forest fires that may burn primarily as a surface fire,</u> spreading along the ground as the surface litter and undergrowth on the forest floor and is engulfed by the spreading flames.
- They are the easiest fires to put out and cause the least damage to the forest. Surface fires create the least amount of destruction.
- <em><u>These fires protects the forest by releasing the nutrients that would otherwise decompose slowly, having little benefit to the ecosystem.</u></em>
- <em><u>Additionally, these fires allow more open spaces for new and different kinds of vegetation to grow and receive sunlight.</u></em>
