While taking photographs in Death Valley on a day when the temperature is 50.0°C, Bill Hiker finds that a certain voltage applied to a iron wire produces a current of 1.000 A. Bill then travels to Antarctica and applies the same voltage to the same wire. What current does he register there if the temperature is -88.0°C? Assume that no change occurs in the wire's shape and size.

When 50.0 mL of 60.0°C water was mixed in the calorimeter with 50.0 mL of 25.0°C water, the final temperature was measured as 40.8 °C. Assume the density for water is 1.000 g/mL regardless of temperature. a. Determine the magnitude of the heat lost by the hot water. b. determine the magnitude of the heat gained by the room temperature water. c. determine the heat gained by the calorimeter d. determine the calorimeter constant.

A. On a day with a temperature of 15 ∘C and a pressure of 785.0 torr , how many grams of peroxyacyl nitrates are found in the air above Los Angeles (1500. km3) if the concentration is 30.0 ppb by moles? The molar mass of the major peroxyacyl nitrate, peroxyacetyl nitrate, is 118.03 g/mol. Express your answer to three significant figures and include the appropriate units. B. Peroxyacyl nitrates contain two relatively weak bonds that can be broken by low-energy...

What is the temperature on a spring day when the resistance is 216.0 Ω?

A carbon resistor is to be used as a thermometer. On a winter day when the temperature is 4.00 C, the resistance of the carbon resistor is 217.3 Ω. What is the temperature on a spring day when the resistance is 216.0 Ω? Take the temperature coefficient of resistivity for carbon to be α = −5.00×10−4 C-1.
