Temperature variations in a graph occur as a result of changing environmental conditions and changing temperature.
Temperature is a physical quantity which measures hotness and coldness of a body. Temperature measures the degree of vibration of molecule in a body. Temperature is measured in centigrade (°C), Fahrenheit (°F) and Kelvin (K) in which Kelvin (K) is a SI unit of temperature. Absolute scale of temperature means Kelvin scale of temperature. relation between Kelvin(K) and centigrade (°C), °C= K - 273.15 from equation, 273.15 K means 0 °C, which is freezing point of water (ice). when we give temperature to the body, its molecule or atom absorbs thermal energy and vibrate about their mean position. Amplitude of vibration get increases as we go on increasing temperature and for higher temperature force of attraction between molecules gets weaker. Hence for higher temperature, due to weaken the force of attraction between molecule, solid goes into liquid state. and further increase in temperature liquid goes into gaseous state.

Explanation:
Answer:
Distance = 1.2 km (Approx)
Explanation:
Given:
Temperature (T) = 30°C
Total Time taken (t) = 3.4 Sec
We know that sound increases in the air sound increase nearly 0.60 m/s for every sound with temperature.
Speed of sound = 331 m/s
So,
V = (331 + 0.60T) m/s
V = 331+(0.60×300C) m/s
V = 349 m/s
Distance = speed × time
Distance = 349 × 3.4
Distance = 1,186.6 m
Distance = 1.2 km (Approx)
Answer: 1 microgram is equal to 0.001 miligrams
Explanation: The factor micro is equal 10^-3 while the factor mili is equal to 10^-3 so to converte the micro to mile we have to multiply by 0.001.
infrared radiant energy is sensed by human skin as warmth. Hence option C is correct.
Radiation in physics is the emission or transmission of energy as waves, particles, or both, via space or a material medium.[1][2] This comprises:
electromagnetic radiation, which includes gamma radiation, x-rays, microwaves, infrared, visible light, and ultraviolet radiation
Particle radiation includes beta radiation, proton radiation, neutron radiation, and other particles with non-zero rest energies.
ultrasonography, sound, and seismic waves (reliant on a physical transmission medium) are examples of acoustic radiation.
gravity radiation, which manifests as gravitational waves or ripples in spacetime's curvature
Depending on the energy of the emitted particles, radiation is frequently divided into ionising and non-ionizing categories. More than 10 eV is carried by ionising radiation, which is sufficient to ionise atoms, molecules.
