What does it mean for heat to be transferred by radiation?
Energy is transferred when molecules absorb electromagnetic waves.
What are objects that absorb sound?
Usually, stuff that is soft will absorb sound.answ2. Sound is a vibration of air molecules, and anything that may be made to absorb energy from the molecules will absorb sound. If the material has soft fibres, and can allow the sound to penetrate easily, (is porous) then the collision of sound molecules with the fibres, will transfer the energy from the molecules to the inelastic fibres, where it will be dissipated as heat.
What happens to molecules when a substance evaporates?
When water molecules at the surface gain sufficient energy they can escape in the atmosphere. Evaporation (not vaporization) occur at any temperature; a higher temperature increase the rate of evaporation. The energy of water molecules increase by a temperature increase and some molecules at the surface can escape in the atmosphere.
How heat is absorbed?
Physical objects absorb heat when the molecules of which they consist absorb energy and increase their velocity. Molecules are always moving, or vibrating in a lattice structure. They can absorb energy through physical collisions with molecules of another object or medium (air, water), or through direct absorption of radiant energy. In either case, the molecules then increase their velocity and the object of which they are a part are said to become hotter, having absorbed heat.
What happens when pigments absorb light?
the electrons of the pigment molecules excite, then the energy dissipates as heat.
What is the plant molecules that absorb energy?
chloroplast's absorb light energy
When chlorophyll a molecules absorb energy the molecules?
release electrons and energy

What are the molecules in plant cells that absorb light energy?
Chlorophyll.

Can evaporation occur when water molecules absorb energy?
Yes, it is correct.
What molecules embedded in the thylakoid membranes absorb light energy?
The Chlorophyll
What happens when a liquid is heated-?
The kinetic energy content increases and the speed of its particles increases.
What is the matter that evaporates water?
When water molecules at the surface gain sufficient energy they can escape in the atmosphere.
How does a liquid evaporates?
The particles inside the liquid absorb heat from their surroundings, causing them to gain enough energy to break the intermolecular bonds that attract them to other liquid molecules and become gaseous.it goes in the air.
