The correct answer is:
A. carry out photosynthesis
Answer:
a.)It will rise faster in cooler air
a.) heat
Explanation:
i
A hot air balloon rises faster if cold air were to surround it due to density differences between the air in the two medium.
- Hot air is less dense as the average kinetic energy of the molecules is greater.
- Cold air is denser.
- This density contrast causes the balloon to move up at a high pressure.
ii. Heat
The average kinetic energy of the molecules in a substance is termed heat.
Heat is a form of thermal energy measured by the kinetic energy possessed by molecules in a substance.
Answer:
2 protons, 2 electrons, and 1 neutron.
Explanation:
Atoms are made-up of sub particles called protons and neutrons found in the nucleus. The protons are positively charge while the neutrons have no charge. The electrons are found in the shell orbitals and are negatively charged and in constant motion. 2 protons will neutralize the negative charge of the 2 electrons in the outer shell.
