True i think but i could be wrong. hope you get it right!
Answer:
When water is boiled water molecules changed into vapors when these vapors condensed water changed into liquid.
So it is reversible reaction.
Explanation:
Water molecules are connected through the hydrogen bonding. When water is boiled the kinetic energy of water molecules increased and point is reached when kinetic energy is so high and water molecules overcome the external pressure and escape from the surface. Thus water molecules convert into vapors.
In case of cooling process extra energy is released. Vapors becomes cooled and kinetic energy decreased vapors are changed into liquid state.
When water is boiled water molecules changed into vapors when these vapors condensed water changed into liquid.
So it is reversible reaction.
Answer:
magnetic north pole
Explanation:
They occur most frequently in a belt of radius 2500 km centered on the magnetic north pole. This so-called auroral zone extends over northern Scandinavia, Island, the southern tip of Greenland and continuing over northern Canada, Alaska and along the northern coast of Siberia.
Answer:
Proteins are the major 'working molecules' within every organism. Among their many jobs, proteins catalyse reactions, transport oxygen and defend organisms from infection- like a doctor for organisms. The precise shape of each protein, and its genes, along with the amino acids it contains, determines what it does, some develop different traits and they may also copy traits of related organisms, which means some organisms may create more protein depending on their traits.
Answer:
The rodents hearing will be less sensitive near and far
Explanation:
In normal hearing, the sound waves travel from the wide tympanic membrane to the ossicles, which causes an increase in the intensity of the sound waves as it gets amplified, therefore, without these the intensity will be less than normal regardless of how far the sound is
