How a lever can increase the force applied without changing the amount of work being done?
Levers are used in everyday life. The force is a lot to do with pivots and moments e.g. a wheelbarrow- the effort force pushes down on the handle (lever) the load is pulled down by gravity and the pivot is the front wheel.
So a lever changes force by the chemical energy in your muscles aiding or fighting gravity.

What else can I help you with?
How may you increase an applied torque without increasing the applied force?
You can increase the applied torque without increasing the applied force by increasing the length of the lever arm or by changing the angle at which the force is applied. This increases the moment arm, which in turn increases the torque for the same amount of force.
Does mass increase as heat is applied?
No. Mass does not increase as heat is applied. Mass is the amount of matter in a body and cannot be changed by any physical or chemical process. Volume will increase when heat is applied.
It is possible to increase the amount of pressure by blank the area where force is applied?
It is possible to increase the amount of pressure by decreasing the area where force is applied. This is known as pressure magnification, where the same amount of force is spread over a smaller area, resulting in higher pressure.
What is an amount of pressure an object can handle without changing?
The amount of pressure an object can handle without changing is called its elastic limit. Beyond this point, the object will undergo permanent deformation or break.
How does an increase in force affect the amount of work don't on an object?
An increase in force applied to an object will result in an increase in the amount of work done on the object. This is because work is directly proportional to force – as force increases, so does the amount of work done.

The surface area
How can a lever increase the force applied without changing the amount of work being done?
Work is force times distance. A lever will increase force, at the cost of distance, or it will increase distance, at the cost of force. Each of these is inversely proportional, so the net force times distance is the same. Said in other words, a lever cannot add to or subtract from work - work is the same in all cases.

How do you alter the volume of gas without changing the amount?
Compress it

What type of pulley changes the direction of the input force but does not change the amount of force you apply?
A fixed pulley changes the direction of the input force without changing the amount of force applied. It is attached to a fixed point and does not move, simply redirecting the force in a different direction.
How can you increase the concentration of a solution without changing the amount of solvent?
You can increase the concentration of a solution by adding more solute while keeping the amount of solvent constant. This can be done by dissolving additional solute in the existing solvent until no more solute can dissolve, resulting in a higher concentration of the solution.
How would changing the amount of glucose available to a cell affect the rate of respiration?
Glucose utilization would increase a little
