In an Experiment to Measure the Thermal Conductivity of a Certain

question 43

Multiple Choice

In an experiment to measure the thermal conductivity of a certain material,a slab of material 10.0 mm thick separates a steam chamber from a block of ice with a square cross-section with dimensions 8.00 cm × 8.00 cm.After 5.00 min of running the experiment,64.0 g of ice have melted.What is the thermal conductivity of this material? The latent heat of fusion of water is 33.5 × 10⁴ J/kg,the latent heat of vaporization of water is 2.256 × 10⁶ J/kg,and both the ice and water are under 1.00 atm of pressure.

• C)0.440 W/m ∙ K
• D)0.620 W/m ∙ K
• E)1.12 W/m ∙ K

Definitions:

Fault Rupture

Fault rupture is the sudden break or fracture along a fault line in the Earth's crust, resulting in the displacement of the ground on either side of the fault.

Oval Shape

An elongated round figure that is broader in the middle and narrower at the ends, resembling a flattened circle.

Seismic Waves

Vibrations that travel through the Earth's interior or along its surface, generated by earthquakes or other seismic events.

Fault Scarp

A steep slope or cliff formed directly by movement along a fault and indicative of the relative motion of the fault blocks.
