If 5 moles of hydrogen gas is heated from 30 degrees C to 60 degrees C at constant pressure how much heat was added to the system?

Using a heat capacity value (@ constant pressure) of 865.51 J/mol. The heat added to 5 moles of hydrogen to raise the temperature from 30 to 60 C would be 4327.6 J or 4.33 kJ.

The heat added can be calculated using the formula: q = nCpΔT, where q is the heat added, n is the number of moles, Cp is the molar heat capacity at constant pressure, and ΔT is the temperature change. Given n=5 moles, Cp for hydrogen gas is approximately 28.8 J/molK, and ΔT = 60°C - 30°C = 30 K, the heat added would be q = 5 mol * 28.8 J/molK * 30 K = 4320 J.

Are nitrogen and hydrogen heated in Haber process?
Yes, they are heated in a ratio of 1:3. The temperature should be 400 degrees celcius. The pressure should be 2-3 atm.
0.783 g of hydrogen gas is placed in an container of volume 657 mL at a temperature of 342 K What is the pressure in ATM?
Using the Ideal Gas Law (PV = nRT), you can calculate the pressure of the hydrogen gas. First, convert the mass of hydrogen to moles using the molar mass of hydrogen. Once you have moles of hydrogen, you can calculate the pressure given the volume, temperature, and the gas constant (0.0821 Latm/molK).
Is solid at 25 degree C and changes to a liquid when heated to 98 degrees C a physical property of sodium?
At normal pressure, yes.
How could you make water boil at 221 degrees Fahrenheit could it include a pressure cooker?
Yes it could. It needs to be heated under pressure and for the increase in temperature required, a pressure cooker will be more than enough.
What happens when a gas is heated beyond 100 degrees?
When a gas is heated beyond 100 degrees, its temperature increases, causing the gas molecules to move faster and collide more frequently. This can lead to an increase in pressure as the gas molecules expand and occupy more space. If the gas continues to be heated, it may undergo phase changes, such as from a gas to a plasma state.
What happens to the pressure of gas when it is heated at a constant heat?
The pressure is higher.
What is a gas that expands when heated?
Any gas will expand when heated, assuming you keep pressure constant.
Why Do Gasses Have Two Specific Heats?
One is for constant pressure, the other is for constant volume. These are not the same; for example, if the pressure is maintained constant, and the gas is heated, the volume changes.
Are nitrogen and hydrogen heated in Haber process?
Yes, they are heated in a ratio of 1:3. The temperature should be 400 degrees celcius. The pressure should be 2-3 atm.
Two cubic meters of a gas at 30 degrees Kelvin are heated at a constant pressure until the volume doubles. What is the final temperature of the gas?
60
What will happen to air if it is heated along a slope element?
Generally, if air is heated, its temperature will increase. And if the pressure remains constant, its density will decrease.

Why is the haber process not run at a high pressure?
because in this process a mixture of nitrogen and hydrogen is heated at 400 to 450c
How much will the pressure increase for one cubic meter of air when heated by one degree c?
Assuming constant volume, the pressure of one cubic meter of air will increase by approximately 0.0365 atmospheres when heated by one degree Celsius. This value is derived from the ideal gas law, where pressure is directly proportional to temperature for a constant volume of gas.
What temperature in degrees Fahrenheit would a fixed volume of gas need to be heated to in order to double its pressure if it starts out at 25 degrees Fahrenheit?
58 F
When does hydrogen expand?
Hydrogen gas can expand when heated, as the molecules gain energy and move more rapidly, increasing the pressure inside a container or a system. This expansion occurs because the kinetic energy of the particles increases with temperature, causing them to move further apart from each other.
Can guppies be kept in a 16 inch aquarium of water that isn't heated quite happily?
Depends what you mean by "isn't heated quite happily" Guppies are tropical fish and need water temps between 72 and 80 degrees Fahrenheit, 75 degrees is a happy medium for guppies. If your room temperature is a constant 75 degrees then no worries. The best thing anyone can do for their fish is to keep the water temperature constant, you don't want it going up and down even a few degrees.
