    temperature it's SI-unit is Kelvin while heat is measured in joules

    Amina Abdallah   Posted on 1 year ago

    Temperature is the degree of hotness or coldness of a body while heat is the form of radiation given out by burning masses

    Neema Mwaga   Posted on 2 years ago

    what is critical angle

    Hamisi Malki   Posted on 2 years ago

    heat is the overall energy of the molecular motion, whereas temperature is the average energy of the molecular motion.

    It states that ; at constant pressure the volume of fixed mass of gas is directly proportional to the absolute temperature

    Hamisi Malki   Posted on 2 years ago


    Charles's law (also known as the law of volumes) is an experimental gas law that describes how gases tend to expand when heated. A modern statement of Charles's law is: When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be in direct proportion.
    .



    Zacharia Masatu   Posted on 3 years ago

    the charles law states that the volume of a gas equals a constant value multiplied by it's temperature as measured on the kelvin scale

    Depends if it is a step down transformer the coils inside it would be set to reduce the electrokinetic energy the wires had been carrying eg a transformer that comes before power being supplied to the locals for home use

    But if it is a step up transformer it means it would be to increase the electrokinetic energy for further transport eg the transformers found near HEP stations or inland power stations the charge is multiplied to allow faster movement and lower resistance rate

    Hamisi Malki   Posted on 2 years ago

    A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another, or multiple circuits

    Zacharia Masatu   Posted on 3 years ago

    a transformer is an electrical device which by the principles of electromagnetic induction transfers electrical energy from one electric current to another without changing the frequency.

    Hamisi Malki   Posted on 2 years ago

    Mutual Inductance is the basic operating principal of the transformer, motors, generators and any other electrical component that interacts with another magnetic field

    Zacharia Masatu   Posted on 3 years ago

    is the interaction of one coils magnetic in another coil as if induces a voltage in the adjacent coil
