The law of conservation of energy is a physical law that states energy cannot be created or destroyed but may be changed from one form to another. Another way of stating this law of chemistry is to say the total energy of an isolated system remains constant or is conserved within a given frame of reference.
In classical mechanics, conservation of mass and conversation of energy are considered to be two separate laws. However, in special relativity, matter may be converted into energy and vice versa, according to the famous equation E = mc2. Thus, it's more appropriate to say mass-energy is conserved.
Example of Conservation of Energy
If a stick of dynamite explodes, for example, the chemical energy contained within the dynamite changes into kinetic energy, heat, and light. If all this energy is added together, it will equal the starting chemical energy value.
Answer: Multicellular organism
Explanation:
Multicellular organisms refer to living things that have more than a single cell as opposed to unicellular organisms such as bacteria. Humans as well as all animals and land plants fall under this classification.
Multicellular organisms can live longer because new cells can be produced when others die. They are also larger due to the presence of many different cells which then specialize in different roles to ensure the survival of the organism.
Answer:
800cm3
Explanation:
This is a general gas law question
Which has the relationship P1V1/T1 = P2V2/T2
P1= P1 in kPa
T1 = T1 in K
V1= 800cm3
V2=?
P2= 2* P1
T2= 2*T1
The volume of gas after the changes (V2), making it as the subject of formula
V2= P1*V1*T2/P2*T1
V2 = P1 *800* 2T1 / 2P1 * T1 ; dividing accordingly, we have
V2 = 800cm3
Solid like a ice cube
Liquid like water
Gas=water vapor orHelium
