If the room temperature is 35°C and the temperature of a hot body in the room cools down to 55°C from 105°C Celsius in just 6 minutes, then how many more minutes will it take to cool down to 45°C?
THERMODYNAMICS SUBJECT NEED ASAP Two spherical vessels of different sizes contain the same gas and are connected by means of a pipe with a valve. Sphere A has a diameter of 5 foot at the given pressure gauge of 50 kgf/cm². Sphere B contains the same gas at 20 kgf/cm² gauge. The valve is opened and when the properties have been determined, it is found out that the gauge pressure is 36 kgf/cm². The temperature at the two vessels before and after opening the valve is maintained at 21.1°C. If the barometric pressure is 750 torr and the gas inside the sphere is nitrogen, find the following: The atmospheric pressure in psi The diameter of Sphere B The total mass of the gas after opening the valve I hope you can all answer this question I know tutor can answer until 4 parts.
