Answer:
There are several ways that scientists communicate our results, including written reports and scientific journal publications, and by giving presentations to our colleagues and the public. One popular venue for scientists to present to colleagues is at scientific conferences.
Explanation:
The amount of kilograms is 0.7718
The answer is: 10
I could be wrong
Answer: 0.0022m3
Explanation:
Initial volume of mercury V1 = 0.002m3 (note that the unit of volume can be cm3, m3, dm3 or liters)
Initial temperature T1 = 20°C
Convert temperature in Celsius to Kelvin
( 20°C + 273°C = 293K)
Final temperature T2 = 50°C
( 50°C + 273°C = 323K)
Final volume V2 = ?
According to Charle's law, the volume of a fixed mass of a gas is directly proportional to the temperature.
Mathematically, Charles' Law is expressed as: V1/T1 = V2/T2
0.002/293 = V2/323
To get the value of V2, cross multiply
V2 = (323 x 0.002) / 293
V2 = 0.646 / 293
V2 = 0.0022 m3
Thus, the new volume of mercury will be 0.0022m3
