Aluminum has a specific heat of 0.900 J/gºC. How much energy in kJ is
needed to raise T of 635 g block from 30.7°C to 82.1°C? *
A)29.4 kJ
B)29,400 kJ
C)571.5 kJ
D).0000275 kJ

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

l dont know l am s sorry

explanation:

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
