Answer:
variable: not consistent or having a fixed pattern; liable to change.
Explanation:
Answer:
22.96 $ per 1 g of gold
Explanation:
We know that 1 g is equal to 0.035 oz.
Now we formulate the following reasoning:
if 1 oz of gold have a value of 655 $
then 0.035 oz of gold have a value of X $
X = (0.035 × 655) / 1 = 22.96 $
The complete question is:
To liquify a fixed amount of gas, one may 1. increase the temperature while decreasing the pressure. 2. increase the volume while increasing the pressure. 3. decrease the temperature while decreasing the pressure. 4. decrease the temperature while increasing the pressure. 5. decrease the volume while decreasing the pressure.
Answer:
4. decrease the temperature while increasing the pressure
Explanation:
The thermodynamics explains the sate of a substance (generally a gas or a liquid), which is its characteristics: temperature, pressure, volume, enthalpy, etc. When they changed, the state changes. Some of these changes may induce a physical change.
A gas has distant and agitated molecules, thus, the pressure is low and the temperature is higher, and a liquid has more close and less agitated molecules, so with higher pressure and low temperature.
Thus, to liquefy a fixed amount of has one may decrease the temperature while increasing the pressure.
Answer:
Miles (mi) or kilometers (km)
Explanation:
This is a big distance and it needs to be measured using a large unit of measurement, unlike feet, yards, or meters.
