A. Conductors. Because in conductors, gap between valence band and conduction band is negligible. Due to this electrons from valence band moves spontaneously to conduction band and on small heating the conductors.

Steam enters a turbine at 400K and exhausts at 360K. Calculate the maximum efficiency. =%

kozerog [31]

The maximum efficiency is 10%

Explanation:

The maximum efficiency of a machine is given by:

$\eta=1-\frac{T_C}{T_H}$

where

$T_H$ is the temperature of the hot reservoir

$T_C$ is the temperature of the cold reservoir

For the machine in this problem, we have:

$T_H=400K$ is the temperature of the hot reservoir

$T_C=360K$ is the temperature of the cold reservoir

substituting, we find the max efficiency:

$\eta=1-\frac{360}{400}=0.1$

So, the efficiency is 0.10 (10%).

Miranda performed an experiment to determine what makes an object sink

NemiM [27]

Answer:

I guess the answer is

-The mass and volume of an object determine if it will sink or float

Explanation:

An object that has a higher density than the liquid it's in will sink. An object that has a lower density than the liquid it's in will float.

density=mass/volume
