A bedroom has a volume of 118 m3 What is its volume in km3?

ruslelena [56]

I believe the problem is just simply asking for us to convert the value from one unit to the other. This case from m^3 to km^3. From the SI units, we know 1 km is equal to 1000 m. We do as follows:

118 m^3 ( 1 km / 1000 m )^3 = 1.18 x 10^-7 km^3

JulijaS [17]

Answer:

Copper>Steel>Aluminium

Explanation:

Hello,

Since the heat capacity accounts for the required heat to increase by 1°C, 1 kg of the metal, copper is the one that has the lower heat capacity, it means that it requires the least amount of energy to warm up (increase its temperature), this could be substantiated via the mathematical definition of heat capacity:

$H=mC(T_2-T_1)$

Solving for $T_2$ :

$T_2=T_1+\frac{H}{mC}$

It means that the lower the heat capacity, the higher the final temperature.

Best regards.
