Equilibrium
what is equilibrium?
a state in which opposing forces or influences are balanced.
lava is hot liquid rock. When lava flows over solid ground, the solid ground beneath it increases in temperature. What happens to the molecules in the solid ground when the temperature is increasing?
The energy of the molecules in the ground increases.
what are molecules?
a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
what is the difference between thermal energy and temperature?
thermal energy is the total amount of molecules in something, and temperature is the speed that the molecules are going.
how can two things reach equilibrium?
if two objects that are initially at different temperatures make physical contact.
Geothermal power plants send water through pipes deep underground where it is hot. This causes the temperature of the water to increase. What happens to the molecules of the water when the temperature of the water increases?
The energy of the water molecules increases.
is there heat, or cold energy?
no
what is temperature?
the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.
how can something change temperature?
adding energy (heating) atoms and molecules increases their motion, resulting in an increase in temperature.
