How can you tell if granite is real?
How is the law of definite proportions important?
How is the law of definite proportions important? The law of definite proportions dictates that a name is always associated with a specific ratio of elements found in a chemical compound. If the ratio of elements is different from that specific ratio then it is not the same compound and therefor has a different name. […]

Why do we use thin gold foil?
Why do we use thin gold foil? For the scattering experiment, Rutherford wanted a metal sheet which could be as thin as possible. Gold is the most malleable of all known metals. It can easily be converted into very thin sheets. Hence, Rutherford selected a gold foil for his alpha-ray scattering experiment. What was most […]
Which best describes the direction of heat?
Which best describes the direction of heat? Explanation: According to second law of thermodynamic, heat flows from higher to lower temperature region. Heat is the transfer of energy from an object at higher temperature to an object at a lower temperature. so energy flows from warmer to colder objects. Which factors affect heat transfer between […]
Is it possible to increase the temperature of a gas without giving it heat?
Is it possible to increase the temperature of a gas without giving it heat? Yes, during adiabatic compression the temperature of a gas increases while no heat is given to it. In compression work is done on the gas i.e. , work done is negative. Hence, internal energy of the gas increases due to which […]
What is the velocity of the piston at bottom dead center?
What is the velocity of the piston at bottom dead center? As the piston reciprocates inside the cylinder, its velocity is zero at the very top (top dead center) and bottom (bottom dead center) of its stroke and quicker mid-stroke (#2). That is, its velocity varies and that change is called acceleration. What is caused […]
Why are clouds flat on bottom and fluffy on top?
Why are clouds flat on bottom and fluffy on top? As warm air rises, the water vapour remains invisible until the air cools enough for it to condense into water droplets. Providing that more air feeds in from below, new cloud will form there and preserve the flat bottom. The existing cloud is pushed upwards, […]
