If we say that gold has a density of 19.32 g/ml, at what temperature is this substance?

Yeah,I've been wanting to ask that too.

a car travel 85km in the first hours at a trip. The car continues to travel for 2 more hours and travel 200 km. Wat wasthe average speed of the car for the trips.

To determine the temperature at which gold has a density of 19.32 g/mL, we need to understand the relationship between density and temperature.

The density of a substance can vary with temperature because most substances expand or contract when heated or cooled. This phenomenon is known as thermal expansion. In general, as the temperature increases, the density of a substance usually decreases.

To find the temperature at which gold has a density of 19.32 g/mL, we need to consult a density vs. temperature chart or equation specific to gold.

Unfortunately, the information provided in the question is insufficient to determine the specific temperature. The density of gold at a given temperature cannot be determined solely based on its value of 19.32 g/mL.
