There's two sig figs: the 1 and the zero. The 10^-2 contributes no sig figs.
Answer: 2.5°C
Explanation:
Initial volume V1 = 5.38 liters
Initial temperature T1 = 36.0°C
Convert temperature in Celsius to Kelvin
(32°C + 273= 305K)
Final temperature T2 = ?
Final volume V2 = 4.68 liters
According to Charle's law, the volume of a fixed mass of a gas is directly proportional to the temperature.
Thus, Charles' Law is expressed as: V1/T1 = V2/T2
5.38/305 = 4.86/T2
To get the value of T2, cross multiply
5.38 x T2 = 4.86 x 305
5.38T2 = 1482.3
Divide both sides by 5.38
5.38T2/5.38 = 1482.3/5.38
T2 = 275.5K
Convert 275.5K to Celsius
(275.5K - 273K = 2.5°C)
Thus, the final temperature is 2.5°C
Answer:
Newton
Explanation:
ive answered like 3 of these types of questions today lol
B. Representative electrons
Firstly it is best to describe the shape and structure of an atom, an atom's system and structure is like of the solar planet, the heliocentric view where the sun is the neutrons and protons and the planets are the electrons. Moreover, the electrons are outside these neutrons and protons surrounding the entire system of its atomic structure. Its movement is like of a planet.
<span>An energy level also known as electron shell, or just shell is a location around an atom where electrons with a specific energy value, or quantum number may be found.</span>
