MA= output force/ input force
MA= 100N/20N
MA= 50
Answer:
228.3°C
Explanation:
Data obtained from the question include:
V1 (initial volume) = 506 cm3
T1 (initial temperature) = 147°C = 247 + 273 = 420K
V2 (final volume) = 604 cm3
T2 (final temperature) =?
The gas is simply obeying Charles' law because the pressure is constant.
The final temperature of the gas can be obtained by using the Charles' law equation V1/T1 = V2/T2 This is illustrated below:
V1/T1 = V2/T2
506/420 = 604/T2
Cross multiply to express in linear form as shown:
506 x T2 = 420 x 604
Divide both side by 506
T2 = (420 x 604) /506
T2 = 501.3K
Now let us convert 501.3K to a temperature in celsius scale. This is illustrated below:
°C = K - 273
°C = 501.3 - 273
°C = 228.3°C
Therefore, the temperature of the gas when the volume of the gas is 604 cm3 is 228.3°C
Ice is cold and water cools down heat, cooking oil isn’t hot unless you add it to heat, corn syrup isn’t hot unless you add it to heat as well so, they’d all lose heat at the same/different rates because they are all cooled beverages/subjects.
Answer: 0.39 moles NaPO4
Explanation: Solution: 1 mole of NaPO4 is equal to its molar mass 118g NaPO4
45.8 g NaPO4 X 1 mole NaPO4/ 118 g NaPO4
= 0.39 moles NaPO4
