MENTION HOW CHANGE IN STATE IS IDENTIFIED |
|
Answer» Changes of state are physical changes in matter. They are reversible changes that do not change matter's chemical makeup or chemical PROPERTIES. Processes involved in changes of state INCLUDE melting, freezing, sublimation, deposition, CONDENSATION, and EVAPORATION. ENERGY is always involved in changes of state. |

Voltage applied in cathode ray experiments |
|
Answer» tion:Cathode rays (electron beam or e-beam) are streams of electrons observed in discharge tubes. If an evacuated glass tube is equipped with two electrodes and a voltage is applied, glass behind the positive electrode is observed to glow, due to electrons emitted from the cathode (the electrode connected to the NEGATIVE terminal of the voltage supply). They were first observed in 1869 by German physicist JULIUS Plücker and Johann Wilhelm Hittorf,[1] and were named in 1876 by Eugen Goldstein Kathodenstrahlen, or cathode rays.[2][3] In 1897, British physicist J. J. Thomson showed that cathode rays were composed of a previously unknown negatively charged particle, which was later named the electron. Cathode-ray tubes (CRTs) use a focused beam of electrons deflected by electric or magnetic FIELDS to render an image on a screen.A beam of cathode rays in a vacuum tube bent into a circle by a magnetic field generated by a HELMHOLTZ coil. Cathode rays are normally invisible; in this demonstration Teltron tube ENOUGH residual gas has been left that the gas atoms glow from luminescence when struck by the fast-moving electrons. |

An exothermic reaction may not be always thermodynamically spontaneous. explain |
|
Answer» Exothermic reactions are generally thermodynamically spontaneous because even if it is accompanied by decrease of randomness ( e.g.,in the CONDENSATION of a gas or solidification ofa LIQUID), the heat releasedis absorbed by the surroundings so that the ENTROPY of the surroundings increases to such an extent that∆S total(+ve) is POSITIVE. The molecules in the vapour state have greater freedom of movement and hence greater randomness than those in the liquid state. Hence, entropy increases in going from liquid to vapour state.hope this is helpful....... |

Why does sulphur dissolve when carbon disulphide is added to a mixture of iron andsulphur but not when it is added to ironsulphide ? |
|
Answer» Sulphur has the PROPERTY to DISSOLVE in carbon disulphide whereas iron does not dissolve and retains its INDIVIDUAL property. In this, Iron and Sulphur particles do not exist separately as such they LOSE their individual property. |
