If measuring experimental results, what can you predict about the work output of a 1200 watt hair dryer? the work output of the
eimsori [14]

Answer: first option, the work output of the hairdryer will be less than the work input.


Explanation:


1) The work output measured in watts is the power of hair dryer measured in joules per second.


2) The hair dryer converts electrical energy from the wall outlet to mechanical and thermal energy: hot wind.


3) Nevertheless, you can never expect a 100% efficiency of the machines: due to friction, some energy is converted into useless energy.


So, efiiviency = power output / power input< 1 ⇒


power output = work output / time


input power = work input / time


⇒ work output / work input < 1


⇒ work output < work input.


Which is the first option: the work output of the hairdryer will be less than the work input

A reaction will most likely occur if the colliding particles have the proper
fenix001 [56]
Answer: a rection will most likely occur if the colliding partilces have the proper orientation and energy.


The reactions occur becasue the molecules collide.


But not all the collisions result in a reaction.


The collisions have to meet some requirements.


Two of the basic requirements is that the collision has enough energy to overcome the activation energy and that the molecules collide in the riight way.


When two molecules react it is necessary that one element of one of the molecules interact when a specific element or group in the other molecule. That is the orientation must be the right one.


Collisions that to not have the proper orientation or enough energy will not cause reaction (changes in the bonds of the molecules).
