A number raised to the third power is negative. What is true about the number?
DaniilM [7]
It had to start off negative. Odd powers of negative numbers remain negative, even powers will always be positive no matter what. Every time you add one to the power, you multiply by another negative, changing the sign.

If you take 50 g of an unknown metal and it takes 1112.5 J of energy to change the temperature
____ [38]

Answer:

0.89 J/g/°C

Step-by-step explanation:

The Heat gained by an object is given in terms of specific heat capacity as:

H = mc(T2 - T1)

where m = mass of the object

c = specific heat capacity

T2 = final temperature

T1 = initial temperature

50 g of an unknown metal takes 1112.5 J of energy to change its temperature  from 20°C to 45°C.

This implies that:

1112.5 = 50 * c * (45 - 20)

1112.5 = 50 * c * 25

1112.5 = 1250 * c

=> c = 1112.5 / 1250

c = 0.89 J/g/°C

The specific heat capacity of the metal is 0.89 J/g/°C
