What are the first 20 elements at room temperature?
H
How will the temperature affect the spontaneity of a reaction with positive h and s?
A high temperature will make it spontaneous.
How will temperature affect the spontaneity of a reaction positive delta h and delta s?
∆G = ∆H - T∆S and for it to be spontaneous, ∆G should be negative. If both ∆H and ∆S are positive, in order to get a negative ∆H, the temperature needs to be elevated in order to make the ∆S term greater than the ∆H term. So, I guess the answer would be "the higher the temperature, the more likely will be the spontaneity of the reaction."
How fast is the speed of sound at an elevation of 20000 feet?
Forget the altitude. Care about the temperature!The speed of sound is dependent on the temperature and not on the air pressure of the altitude. At 20 degrees celsius or 68 degrees Fahrenheit the speed of sound is 343 m/s or 1236.3 km/h or 1126.7 ft/s or 667.1 knots.Scroll down to related links and look at "Speed of sound - temperature matters, not air pressure".Here is an easy calculator if you know the temperature. Do not care about the altitude!Scroll down to related links and look at "Calculation of the Speed of sound in air and the important temperature".Asume a temperature of -70 degrees Celsius for a height of 44,000 feet.
When you fly in an airplane at night in smooth air there is no sensation of motion even though the plane may be moving at 800 km per h Why is this?
you are isolated from the air outside, in effect you are in a slipstream, plus only under acceleration or decelaration will you feel any forces, not at constant velocity

There are a number of sites where one can find information on Astra H car specifications. One site that is very good is the "ultimatespecs" website which offers specs for different models and different years.
Can anyone tell me why my 99 grand prix external temp is still displaying the wrong temp after i replaced the external ambient sensor for dual climate control?
Does it always give false readings or just at times near start up? thought this may helpThe outside air temperature sensor is located in the frontgrill area under the front bumper of the vehicle. The HAVC control head usesthis sensor to receive information on ambient air temperature. With this information,the HVAC control head will give the driver the outside air temperature on the digital display. If the outside temperature increases, the displayed temperaturewill not change until:The vehicle's speed is above 32 km/h (20 mph) for approximatelyone and a half minutes.The vehicles speed is above 72 km/h (45 mph) for approximatelyone minute.These delays help prevent false readings. If the displayed temperaturegoes down, the outside temperature display is updated immediately. If thevehicle has been turned off for more than three hours, the current outsidetemperature will be shown when the vehicle is started. If it has been turnedoff for less than three hours, the temperature will be recalled from the previousvehicle operation.
