Answer: The lower temperature reduces molecule speeds, reducing the number of effective collisions.
Explanation:
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).
Answer: Glaciers can erode around rock. They shift over time so it causes the rock (or glacier) to erode. If it erodes enough it creates a valley. The glacier causes it to go deeper and deeper! That is how valleys are made!
Then product forms at the cathode is Fe metal
Fei3 undergo dissociate to form fe^ 3+ + 3I^-
Fe^3+ move to the negative electrode(cathode) where they are reduced to metallic iron by gaining 3e-
that is Fe^3+(aq) + 3e- = Fe(s)
