How much heat is given off by 1,000 kg of lead when it solidifies at its melting point? (see the table)
substance: heat of fusion(j/kg)
copper 2.66 x 10^5
iron 2.66 x 10^5
silver 1.04 x 10^5
lead 2.04 x 10^4
gold 6.30 x 10^4
answers:
(a): 4.90 x 10^-2 j
(b): 2.04 x 10 j
(c) 2.04 x 10^8 j
(d) 2.04 x 10^7 j
(p. s x=multiply its not an exponent btw)

Estimate the kinetic energy of the neptune with respect to the sun as the sum of the terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. [assume the neptune is a uniform sphere with mass = 1.0×1026 kg , radius = 2.5×1010 m , rotation period 16.1 h , orbital period 6.01×104 d and is 4.6×109 km from the sun.]
