Question

units of energy..........

Answer 1

joule ......J


NEWTON METERE......Nm

KILOGRAM METER PER SECOND SQUARE .....Kg m/s^2

Answer 2

1 calth = 4.184 J, thermochemical calorie

1 cal15 ≈ 4.1855 J, calories to heat from 14.5 °C to 15.5 °C

1 erg = 10−7 J, cgs [centimeter-gram-second] unit

1 eV ≈ 1.60218 × 10−19 J, electron volt

1 Eh ≈ 4.35975 × 10−18 J, Hartree, atomic energy unit

1 Btu = 1055.06 J, British thermal unit according to ISO, to heat 1 pound water from 63 °F to 64 °F

1 tce = 29.3076 × 109 J, ton of coal equivalent, 7000 kcalIT

1 toe = 41.868 × 109 J, ton of oil equivalentUnits of Energy

James Prescott Joule (1818 − 1889) was a self-educated British physicist

and brewer whose work in the midnineteenth century contributed to the establishment of the energy concept. The international unit of energy bears

his name:

1 Joule [J] = 1 Watt-second [Ws] = 1 V A s = 1 N m = 1 kg m2s−2.

It takes about 1 J to raise a 100-g-apple 1 m. Energy units can be preceded

by various factors, including the following:

kilo (k=103), Mega (M=106), Giga (G=109), Tera (T=1012), Peta (P=1015),

Exa (E=1018). 10000 kcalIT
