Answer:
Option C. 296K
Explanation:
T°C = 23°C
To covert the above to Kelvin temperature, use the following equation
T(K) = T°C + 273
T(K) = 23 + 273
T(K) = 296K

Answer:
Density = 8.92 g/cm³
Explanation:
Density shows the relation of the mass and volume of a determined object. We have this deffinition:
Density = mass / volume
First of all, we calcualte the volume of the block of copper metal, with the data given:
8.4 cm . 5.5 cm . 4.6 cm = 212.52 cm³
Now we replace at the density formula:
Density = 1896 g /212.52 cm³ = 8.92 g/cm³
