Answer:
80g=0.08kg
20cm=0.02m
density=m/v
= 0.08/0.02
=4kg/m^3
it is less than density of water so it floats
Answer:
D. Pressure and temperature.
Explanation:
The answer is D because when water molecules (H2o) have heat and pressure added it will boil. For exampe if your cooking pasta, you add water to your pan and when you add heat and put the lid of the pan it will boil.
Question:
The options are;
a. Temperature
b. Thermal Energy
c. Hotness
d. Fire Energy
Answer:
The correct option is;
b. Thermal energy
Explanation:
A burner on a stove produces thermal energy which is used to raise the temperature of the metal container (kettle, pot or pans) in which items are placed for heating.
Thermal energy is the internal energy of the system given off as heat which when transferred from one body to another causes the temperature of the receiving body to rise. Thermal energy in a burner is given off when the gaseous fuel reacts or burns in the presence of or with oxygen to produce carbon dioxide and water vapor in an exothermic reaction.
4C + 5H₂ + 13/2O₂ (-125 kJ) → C₄H₁₀ + O₂ → CO₂ + H₂O (-2877 kJ).
The answer is (3) its aqueous solution conducts an electric current. The definition of electrolyte is a substance that will ionize when dissolved in suitable ionizing solvents such as water.
