Science > Physics > Thermometry > Numerical Problems on Temperature Scales In the previous article, we studied measurement temperature, various scales to measure temperature viz: Celsius scale, Fahrenheit scale, and Kelvin scale, and also interconversion of temperature in different temperature scales. In this article, we shall study, the concept of specific heat and latent heat […]

Concept of Temperature
Science > Physics > Thermal Properties of Matter and Thermodynamics > Concept of Temperature In last article we have discussed concept of heat. In this article, we shall study the concept of temperature, different temperature scales, and convert temperature in different temperature scales. Defining Temperature: Temperature can be defined in several ways: It is measured […]

Discovery of Proton and Neutron
Science > Physics > Nuclear Physics > Discovery of Proton and Neutron Before the discovery of the atomic nucleus, there were ideas that all atoms are composed of hydrogen atoms (called by William Prout “protyles”). This hypothesis is known as Prout’s hypothesis. According to this hypothesis, the hydrogen atom was the only truly fundamental particles, […]

Concept of Radioactive Decay
Science > Physics > Nuclear Physics > Concept of Radioactive Decay Transformation of radioactive element into another element (radioactive or non-radioactive) is known as radioactive decay or disintegration. In radioactive decay, the nucleus of a radioactive element called parent undergoes a spontaneous change accompanied by the emission of radiation and the formation of the nucleus […]

Electric Potential
Science > Physics > Electrostatics > Electric Potential Electric Potential at a Point: The electric potential at any point in the electric field is defined as the work that must be done by the external force to move unit positive charge from infinity to that point without acceleration. If W is the work done in […]

Change of Phase
Science > Physics > Themodynamics > Change of Phase In this article, we should study the concept of phase, change of phase anfd the triple point of water. Phase: The phase of a substance is defined as its form which is homogeneous, physically distinct and mechanically separable from other forms of the substance. The term […]
