Answer:
No, in science their meanings are not the same as their everyday meanings.
Explanation:
In Science, Precision and Accuracy are defined as,
Accuracy:
Accuracy is the value which is closest to the known or standard value.
Precision:
While, Precision is the value of closeness of two measured values to each other.
Example:
Let suppose in Chemistry Lab you weight an object as 50 g. While the actual weight of that object is 30 g. It means your reading is not accurate.
On second measurement you find that the object weight is 31 g. This time your reading is not precise.
Answer:
0.13 atm
Explanation:
Using the Ideal Gas Law; PV=nRT, we can rearrange to solve for pressure.
P=nRT/V
P is pressure, n is number of moles (0.023), R is a constant (0.08206 L*atm/mol*K), T is temperature in Kelvin (293.15K) and V is volume, 4.2 L.
So, plugging in;
P=(0.023mol)(0.08206L*atm/mol*K)(293.15K)/(4.2 L)
P=0.1317 atm
P=0.13 atm; multiply by 760 to get to Torr or mmHg.
The chemicals combination of the atoms is called a compound. The bond is formed between the atoms of each of the reacting elements thereby forming a new substance altogether. The compound will often exhibit different characteristics from the originating elements.
B. the frogs are a limiting factor for the gnats
the frogs limit the reproduction of the gnats, and therefore with less frogs the gnat population can increase
Explanation:
Pressure of a gas is the combined force with which the molecules bombard a unit area of the wall of the container.
1 atm = 760mmHg
= 760torr
= 101325Pa
= 101325Nm⁻²
1mmHg = 1torr
1Pa = 1Nm⁻²
101.325 kPa and 101,325 Pa are the same
1000Pa = 1kPa
101,325 Pa and 1 atm
1atm and 101.325 kPa
