According to the Delaware River Port Authority, the total length of the Walt Whitman Bridge is nominally 11,982 feet. Assuming that the bridge was made entirely of steel, by how many meters does the bridge’s length change as its temperature rises from a winter temperature of 5°F to a summer temperature of 105 °F? Length change = _________meters.

An arctic weather balloon is filled with 49.6L of helium gas inside a prep shed. The temperature inside the shed is 11.°C. The balloon is then taken outside, where the temperature is −39.°C. Calculate the new volume of the balloon.You may assume the pressure on the balloon stays constant at exactly 1atm. Round your answer to 3 significant digits.

2.2 kg of ice (solid phase of water) at -10°C is heated under atmospheric pressure. Answer the following questions. Use the following values for your calculation. specific heat of ice: 2.1 kJ/(kg °C) specific heat of water: 4.2 kJ/(kg °C) specific heat of vapor: 2.0 kJ/(kg °C) latent heat of fusion: 334 kJ/kg latent heat of vaporization: 2260 kJ/kg    How much heat is required to raise the temperature of the ice to melting point T = 0°C?  How much heat is required to change the phase of the ice to liquid water?  How much heat is required to raise the temperature of the liquid water to boiling point T = 100°C?

Instructions: Provide the answer in standard scientific notation with SI units that do not have prefixes (except for kg). Provide final answer with correct units and 3 significant figures. Please avoid round off error

Luis and Salman are trying to increase the temperature of a substance by heating it. . What is the quantity of heat in kilojoules required to raise the temperature of 1.2 kg of the substance from3°C to 110 °C at a pressure of 1.0 atm? Please keep three significant figures. Useful information: Melting point = 293 K heat of fusion = 3.90 x 104 J/kg. boiling point is 423 K heat of vaporization 7.80 x 104 J/kg (at a pressure of 1.0 atm). The specific heats for the solid phase is 600 J/(kg K) The specific heats for the liquid phase is 1000 J/(kg K) The specific heats for the gaseous phase is 400 J/(kg K)

The temperature at a point (x, y) on a flat metal plate is given by T(x, y) = 96/(2 + x² + y2), where T is measured in °C and x, y in meters. Find the rate of change of temperature with respect to distance at the point (1, 3) in the x-direction and the y-direction. (a) the x-direction 1 °C/m (b) the y-direction Need Help?
