What is the net heat current in radiation of an Ice cube at 0 °C if the surrounding air is at 20°C? The ice cube has sides of length 2.50 cm, the emissivity of ice is 0.96 and the Stefan-Boltzmann constant is o = 5.67 x 10-8 Watts/m2Kª. Is the heat flow out or into the ice cube, explain?

You are standing in Death Valley, California on a summer afternoon, and the temperature is well above 100 degrees.  You place a piece of asphalt (Specific Heat = 0.915 J/g°C) and a piece of concrete (Specific Heat = 0.879 J/g°C) on the ground next to one another.  If you were to crack an egg onto each surface, which one would be more likely to fry the egg completely?  Please explain.

A steel measuring tape used by a civil engineer is 50metres long and calibrated at 200C. The tape measures a distance of 35.694m at 350C. What is the actual distance measured? D = DLLT()0) a Coefficient of linear expansion of steel a = 1.2 x10-5 oC-1

Which of the following is an example of heat transfer by radiation? When you walk on your tiled, kitchen floor, your feet feel cold. Someone warming their hands next to a fire. Touching a cold window with your warm hands. Someone warming their hands above a fire. Heat transfer through hot fluids rising and cold fluids sinking in a pot of boiling water.

Select all the correctly defined terms. (Hint: do not select the ones that are incorrectly defined) Law of conservation of energy presumes the total energy content of the universe is constant. Kinetic energy is attributed to the motion of the obicet and depends on the mass of the object and its velocity. O Potential cnergy is the energy associated with position or composition. Heat involves the transfer of energy between two objects due to a temperature difference. Work is a force acting over a distance Could also be transfer of cnergy from onc form to another

Specific heat capacity of a substance is equal to The amount of heat required to raise the temperature of a 1 kg of a substance by 1 k O The amount of heat required to change the phase of a substance from solid to liquid without any change in temperature O The amount of heat required to change the phase of a substance from liquid to gas without any change in temperature O The amount of heat required to raise the temperature of a substance by 1 k
