Answer:
Explanation:PRESSURE: atmospheres or mm Hg; 1 atm = 760 mm Hg
TEMPERATURE: Kelvin, K, which is o
C + 273
STP: Standard Temperature and Pressure: 273 K and 1 atm (or 760 mm Hg)
BOYLE'S LAW (temperature is constant): PV = constant
This is an inverse relationship: if one variable increases the other must
decrease.
CHARLES' LAW (pressure is constant): V = constant x T
This is a direct relationship: if one variable increases so does the other.
GAY-LUSSAC'S LAW (volume is constant): P = constant x T
This is a direct relationship: if one variable increases so does the other.
<h2>Every one of this with the constant</h2>
False- you have to have a hearing with a judge to see how long it is revoked for.
Explanation :
Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
The rule apply for the multiplication and division is :
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
The rule apply for the addition and subtraction is :
The least precise number present after the decimal point determines the number of significant figures in the answer.
(a) 628 × 342
The correct answer is,
(b) (5363 × 102) × (7.4 × 103)
The correct answer is,
(c) 28.0 ÷ 13.483
The correct answer is, 2.08
(d) 8119 × 0.000023
The correct answer is,
(e) 14.98 + 27,340 + 84.7593
The correct answer is,
(f) 42.7 + 0.259
The correct answer is,
Liquid has a definite volume but no specific shape<span />
It won't be possible for me to answer this question if there is no context. I tried to find a similar question and I came up with one. The problem is shown in the attached picture. From the given choices, all their units are atm*mL. So, that means that P*V. The answer could only be (2) or (4). Let's try the data in the table to find out.
PV = (0.5 atm)(1000 mL) = 500 atm*mL
PV = (1 atm)(500 mL) = 500 atm*mL
PV = (2 atm)(250 mL) = 500 atm*mL
<em />
<em>Thus, the answer is choice (2).</em>
