Answer:
The heat needed to warm 406.0 mg of cyclohexane from 33.5°C to 38.9°C is 209.22 Joules
Explanation:
Where:
Q = heat absorbed or heat lost
c = specific heat of substance
m = Mass of the substance
ΔT = change in temperature of the substance
We have mass of cyclohexane = m = 406.0 mg = 0.4060 g
( 1 mg =0.001 g)
Specific heat of cyclohexane = c = 1.85 J/g°CK
ΔT = 38.9°C - 33.5°C = 5.4°C =5.4+273.15 K = 278.55 K
Heat absorbed by the cyclohexane :
The heat needed to warm 406.0 mg of cyclohexane from 33.5°C to 38.9°C is 209.22 Joules
Is the water line of boat when someone boards or leaves it.
Answer:
C). 373 Kelvin, 100 degrees Celsius, 212 degrees Fahrenheit
Explanation:
Kelvin and Celsius are related using the equation K = C + 273.
Celsius and Fahrenheit are related using the equation F = (9/5) * C + 32.
This means that Kelvin and Celsius have to differ by 273, in which only B and C fit that description.
Then you can look at the Celsius and Fahrenheit readings from B and C and apply the equation F = (9/5) * C + 32. For B, you take 0 degrees Celsius and substitute it in for C to get F = (9/5) * 0 + 32, in which you get 32 degrees Fahrenheit and <em>not </em>the 212 degrees in answer B. For C, you do the same: F = (9/5) * 100 degrees Celsius + 32 = 212 degrees Fahrenheit, which does agree with the answer. Therefore, it must only be C.
Answer:
c
Explanation:
The number of jobs in renewable energy worldwide increased in 2020, despite the huge economic disruptions caused by the pandemic, with the growing industry holding up better than fossil fuels. so which means reasourses are limited because of the pandemic and prises on thing rising.
