We turn on a heater that delivers 150 watts (150 J/s) to  1.9 kg of water in a lab experiment.  After 33 seconds, how much will the water temperature have increased?  Give your answer in degrees Celsius.     Hint: The specific heat of water is 4186 J/kg °C.

A particular pair of human lungs have a volume of 2.5 L when inflated. At this volume, the temperature inside the lungs is 97.9°F. If the temperature of the air outside the lung is 44.8°F, what volume of cooler outside air is being inhaled and warmed?

Consider a graph of temperature in degrees Celsius, C, versus temperature in degrees Fahrenheit, P, and assume that this graph is a straight line. It is known that 100°C and 212° F correspond to the temperature at which water boils. Similarly, 0°C and 32°F correspond to the freezing point of water.a) What temperature in degrees Fahrenheit does 20°C correspond to?b) What temperature in degrees Celsius does 100° F correspond to?c) What temperature has the same value in degrees Fahrenheit and in Centigrade?

At the peak temperature on a sunny but cold day, the speed of sound in air was measured to be about 316.m/s. What was the air temperature? Speed of Sound in Air Tx 273.15 v(in m/s) = 331 . where Tg is the temperature in Kelvin. Also recall Tc = Tg– 273.15 where Te is the temperature in Celsius. A. -25.18°C D. -27.43°C В. -29.4°C E. -26.62°C С. -24.2°C F. -28.44°C
