Their 'degrees' are the same size. The difference between the Celsius
and Kelvin scales is their zero-point. Zero Kelvin is the absolute zero of
nature and Physics. Zero Celsius is the melting/freezing point of water,
273.15 higher than absolute zero.
Answer:
The maximum pressure that will be attained in the tank before the plug melts and releases gas should be less than 74.26 atm.
Explanation:
To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
![\frac{P_1}{T_1}=\frac{P_2}{T_2}](https://tex.z-dn.net/?f=%5Cfrac%7BP_1%7D%7BT_1%7D%3D%5Cfrac%7BP_2%7D%7BT_2%7D)
where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:
![P_1=49.2 atm\\T_1=39.0^oC = 312.15 K\\P_2=?\\T_2=198^oC=471.15 K](https://tex.z-dn.net/?f=P_1%3D49.2%20atm%5C%5CT_1%3D39.0%5EoC%20%3D%20312.15%20K%5C%5CP_2%3D%3F%5C%5CT_2%3D198%5EoC%3D471.15%20K)
Putting values in above equation, we get:
![\frac{49.2atm }{312.15 K}=\frac{P_2}{471.15 K}\\\\P_2=74.26 atm](https://tex.z-dn.net/?f=%5Cfrac%7B49.2atm%20%7D%7B312.15%20K%7D%3D%5Cfrac%7BP_2%7D%7B471.15%20K%7D%5C%5C%5C%5CP_2%3D74.26%20atm)
The maximum pressure that will be attained in the tank before the plug melts and releases gas should be less than 74.26 atm.
Answer: D
The final velocity of the object will be directed north of east
Explanation:
Glucose is a simple sugar.
Its chemical formula is C₆ H₁₂ O₆ .
That tells you that every glucose molecule is made of 6 atoms of carbon,
12 atoms of hydrogen, and 6 atoms of oxygen.
Work = force x distance
= 100N (force) x 0.5m (distance)
= 50J
