A vessel closed by a piston contained mass of gas. The volume was reduced to one half of its initial valueby pushing in the piston while the temperature of the gas remained unchanged. State the changes when the pressure of gas changes

How can activation energy be reduced?
Allows more molecules to overcome the activation enthalpy, so there are more molecules available to collide with each other, increasing the chance of a successful collision, increasing the number of collisions per second and with it the rate of reaction.
What is relative velocity observer moving 3.2meters per second toward object moving toward you at 1.4meters per second?
Ans;- 4.6 meters per second. This assumes they are heading 'Directly' towards each other, and the 'Impact speed' will be the sum of their individual speeds !. But If they are approaching each other on a collision path, but at an angle, then one of the speeds will be vectored, by trigonometry to reduce its approach speed, according to the angle.
How are relay proteins activated?
They can be activated by signaling molecules such as second messengers.
Why are bumper cars an example of Newtons first law?
It points to the law of linear conservation of momentum, the total momentum after collision is the same as before the collision, say each car including driver has a mass of 200 kg, car A is moving at 5 metres / second, car B is stationary. Momentum of the moving car makes up all the momentum prior to collision and is = mass * velocity = 200 * 5 = 1000 kg.m/s, assuming an elastic(or perfect) collision, in which no energy is lost as heat or noise, the momentum after the collision will still be 1000 kg.m/s, but the mass will have increased to 400 kg (total of both cars), so the equation after collision: 1000 = 400 * velocity, velocity = 1000 / 400 = 2.5 metres / second
How many protein molecules can one ribosome produce per second?
Ribosomes produce about 2,000 proteins per second or 173,000,000 per day. Astounding beyond all reason. Multiply that by the number of cells in the human body, and you get 1.28x10 to the 21 proteins manufactured each day. Cells also destroy the same number. They are constantly renewing and replacing their proteins.
What is a collision bulkhead?
It is a safety barrier or wall between two compartments or rooms. In the event of an impact it can reduce damage to the second compartment.
Second collision occurs when?
After the first collision.
In a colision the second colision is when the unsecured driver strikes the inside of a vehicle?
In a collision, the second collision is when an unsecured driver strikes the inside of the vehicle.
Why third order reaction usually not is not possible?
Third order reactions imply reaction between three molecules, which implies collision between three molecules. From a probability standpoint this is much less likely than, say, a second-order reaction, where only two molecules must come together.
How can activation energy be reduced?
Allows more molecules to overcome the activation enthalpy, so there are more molecules available to collide with each other, increasing the chance of a successful collision, increasing the number of collisions per second and with it the rate of reaction.
Are you more likely to survive a collision if you are thrown from the vehicle?
No. "Experts have found it is usually the second collision that injures and kills people. When one car hits another car or object, this is the first collision. The second collision occurs when unbelted occupants are thrown into or around the car's interior or thrown from the vehicle. If an occupant is seat belted, there is no second collision" From http://www.fas.org/irp/agency/aia/cyberspokesman/99-07/safety2.htm
How 2 divide a mixed number by a mixed number?
Change them into improper fractions. Invert the second fraction and multiply them together. Reduce if necessary.
Which type of collision occurs when a baseball bat hits a baseball?
inelastic collision The formulas for the velocities after a one-dimensional collision are: where V1f is the final velocity of the first object after impact V2f is the final velocity of the second object after impact V1 is the initial velocity of the first object before impact V2 is the initial velocity of the second object before impact M1 is the mass of the first object M2 is the mass of the second object CR is the coefficient of restitution; if it is 1 we have an elastic collision; if it is 0 we have a perfectly inelastic collision
Is The second collision is when the windshield or steering column stops you if you do not wear your safety belt.?
true
How many seconds to avoid rear end collision?
Three second rule is correct
What is the second most common drug found in the bodies of collision victims?
Marijuana
