Answer:
The volume will not change. This belongs in Ripley's Believe It or Not.
Explanation:
The combined gas law can be used to model both the initial (1) and ending (2) states of a gas when pressure (P), temperature (T) and/or volume (V) change, but the number of moles does not. Remember that temperature must always be in Kelvin.
P1V1/T1 = P2T2/T2
Rearranging for V2:
V2 = V1(T2/T1)(P1/P2)
I've arranged the pressure and temperature terms as ratios. This makes it easier to see what impact changes will have, plus the units conveniently cancel for both.
(V2) = (1 L)(T2/T1)(P1/P2)
We are told that P2 and T2 are both doubled:
(T2/T1) = 2
(P1/P2) = 1/2
V2 = (1 L)(T2/T1)(P1/P2)
V2 = (1 L)(2)(1/2)
V2 = (1 L)(2)(1/2)
V2 - 1 L
The volume does not change. Bummer.
Answer:
Organ systems & their main functions
Explanation:
The chest bones Rib Cage & spine - protects the vital organs (heart, lung,liver) from injury & provides structural support for body.
Skin is the body's first line of defense & keeps the body warm. In case of any invading infection, fever - body temperature rise fights it.
Circulatory system (containing heart) & its body fluid blood - transports nutrients and oxygen to body cells
Endocrine system regulates growth, produces hormones - that target organs via bloodstream.
Latent heat of fusion is the heat required to change 1 kg of a solid substance into liquid state at the melting point of the substance. For example, amount of heat required to melt ice at 0° C into water at 0° C, will be known as the Latent Heat of Fusion of ice.
Answer: make a drainage system or make sure that the ground does not absorb the water from the rain and cause a landslide.
Explanation: To prevent frequent landlides you have to make suee there is and area for the rain to go so it does not get stuck in the mud and destabalize the mud
<span>During an experiment, given that other elements that make up the compound are identified, an unknown element x can easily make separate if certain properties of that unknown element is exhibited in the experiment. So, the first thing to do would be to identify the compound, identify and isolate all the knowns and one can test to see the properties which the unknown element is giving and make a reasonable deduction from that.For example if we were testing for the presence of water in Copper(II) sulfate . if water is in the sample that we were testing for, we will see that the sample will turn blue because of the presence of water</span>
