If a process is carried out at constant pressure P and the volume V of the system decreases then V is negative positive and the work w is negative positive zero?

In this case, V would be negative, and work w would be positive.

Why the slope of temperature versus pressure graph is positive in some cases and negative in other cases?
If the pressure is increasing then the slope is positive. If the pressure is decreasing then the slope is negative.
What things have positive and negative numbers?
temperature battery magnet blood pressure the earth rotations
Dose a positive pressure drain need a trap?
A trap on a positive drain is used to avoid the 'contaminated' air in a HVAC system from traveling through the condensate line and entering into areas where it is unwanted. The trap becomes necessary when one condensate line is used for multiple units, especially if it is tied to other negative pressure drain traps. The negative pressure drain traps may not drain properly if they have to overcome the positive non- trapped pressure of another unit. It allows the condensate to drain more evenly, as well. Without a trap, the positive pressure from the unit can blow air through the drain with the water and cause 'spitting.' A trap on a positive pressure system may not always be necessary, but it is good practice to trap every drain and trap it properly. There are guidelines for both positive and negative pressure traps. Always follow the manufacturers recommendations.
Why is the slope of water negative?
For water the line has a negative slope (vs carbon dioxide). This explains why ice floats since volume decreases with increasing pressure as we move upward on the phase diagram from solid to liquid water, the volume occupied by H20 decreases and thus water must be increasing in density.
How you go on with your peers?
The best way to go on with your peers is to only engage in activities that are positive, and always resist negative peer pressure.
When temperature of a gas decreases at constant volume it?
...pressure decreases.
When the temperature of a gas decreases a constant volume its?
...pressure decreases.
When the temperature of a gas is constant will the volume increase or decrease as the pressure decreases?
as the pressure decreases the volume of gas increases at constant temperature
When the temperature of a gas at constant volume decreases it's?
...pressure decreases.
What happens to the pressure of a confined gas at a constant temperature when the volume is reduced by half?
pressure decreases
When the pressure of a gas at a constant temperature is increased the volume of the gas decreases when the pressure is decreased the volume increases?
decreases
When the temperature is constant will the the volume of a gas decrease as the pressure decreases?
At constant temperature p.V=constant, so pressure INcreases when decreasing the volume.
What can you say about pressure and volume according to boyles law?
For a given mass at constant temperature, the pressure time tghe volume is a constant. pV=C
What gas law does it say that when the pressure of a gas is at constant temperature it is increased its volume increases or decreases?
decreases
When the pressure on a gas increases at constant temperature its volume?
decreases
At constant temperature if the volume of a gas decreses what happens to the pressure?
At constant temperature if the volume of a gas decreses what should I do now
There is any special case that when pressure decreases volume also decreases?
Sure, if temperature isn't held constant.
