All thermos containers have a thin region of vacuum between the outer casing and the inner reservoir. It takes a long time for very hot or very cold liquids inside the thermos to reach room temperature because (A) vacuums have a low thermal conductivity (B) vacuums have a low heat capacity (C) radiation cannot travel across a vacuum (D) the second law of thermodynamics forbids rapid temperature changes

(answer number 4-8 & main question) Two vessels of different shape and sizes are connected by means of a pipe with a valve. Vessel A has a diameter of 4 ft and the length is 1.8 m at the given pressure gauge of 1476.4 in Hg and temperature of 82°F. Another vessel spherical in shape contains the same gas at 15,000 torr gauge and 18°C. The valve is opened and when the properties have been determined, it is found out that the gauge pressure is 35.7 kgf/cm2 and the temperature is 21°C. If the barometric pressure is 755 mm Hg, find the following: Volume of Vessel A in in3 - done Pressure at Vessel A in psia - done Temperature at Vessel A in °R - done Pressure at Vessel B in psia Temperature at Vessel B in °R Pressure of the gas when mixed in psia Temperature of the gas when mixed in °R Atmospheric pressure in psi Main Question: What is the diameter of the spherical tank in inches if the gas is carbon dioxide?
1. The boiling temperature of water is 100 °C. If you put boiling water in a mugplaced at the table top, you observed that after some time the water cools down,decreasing the temperature of water in the mug. Why is this so? Explain using theZeroth Law of Thermodynamics. What happens to objects when temperature increases? For instance, a jar cover an be removed by putting the cover in hot water. Why is this so?
I need a KPI for a project that consists of two partsThe first is glasses that monitor objects around them, and alert the person when an object is within the specified distanceThe second part is a glove that senses the heat from a distance. When the temperature reaches above the permissible limit, the person is alerted by means of a vibration motor.The purposes used in the first part:Spectacle shaped frame3 ultrasonic sensors2 vibration motors Arduino Pro NanoThe purposes used in the second part:The glove consists of two layers3 temperature sensorsMotor vibrationArduino Pro NanoMicro-nano charging baseWorking principle of each part:part One ::Objects that are within the distance on which the Ultrasonic has been programmed are monitored, where there is to the right of the glasses and the left of the glasses, and to the front of the Ultrasonic glasses, and there is a vibration motor on the right of the glasses and the left of the glasses.

An electric heater producing 260 W of heat is used to warm up a room containing 7 m3 of air. If we assume the room is perfectly sealed and there is no heat loss through the room boundaries, such that all of the heater output goes into increasing the air temperature, how long will it take to heat up the air in the room from 5.0 °C to 24.1 °C? Give your answer to the nearest minute and assume that the specific volume (v = 0.85 m3/kg) and specific heat capacity at constant volume (cv = 1.005 kJ/(kg K)) remain constant throughout the heating process.
