OK so the answer to your question will be option D. because chemical energy is being transferred as heat and light
The volume of a sample is its unique property, which can be defined as the mass of the material per unit volume of that material. Now as per Archimedes law if a material is submerge in a liquid the increased volume of the liquid will be equivalent to the volume of the material.
Here due to addition of the Jade the volume of the liquid increases from 50 to 60.5 mL. Thus the change of the volume is (60.5-50) = 10.5 mL, which will be equivalent to the volume of the Jade. Thus the volume of the Jade is 10.5 mL and its density 3.3 g/cm³. Now as 1 mL = 1 cm³ thus the density can be rewritten as 3.3 g/mL. So 1 mL of the Jade has the mass 3.3 g, thus 10.5 mL of the Jade will have (10.5×3.3) = 34.65 g of mass.
The mass of the piece of Jade is 34.65 g.
Elements are the simplest building blocks you can break matter down into using purely chemical methods. They are a pure substance made up from only one type of atom.
When you mix elements together these form compounds. The important difference is that as they are a mixture of more than one type of element, they CAN be broken down into more simple substances using chemical means!
As such Hydrogen or Oxygen cannot be simplified chemically (they are therefore elements), however dihydrogen monoxide (H2O or water) is a mixture of these elements that can be broken down using chemical means and so is a compound.
Answer: The heat moves through the atmosphere through the process of radiation.
Explanation:
There are three modes of transfer:
1. Conduction: This type of heat transfer happens when there is direct contact between the two object.
2. Radiation: This type of heat transfer happens when there is direct transfer of energy through space.
3. Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas) in which convection currents are produced due to the movement of hot fluid upwards and cold fluid downwards.
Thus heat moves through the atmosphere through the process of radiation
