Answer:
Firsthand association assigns energy throughout conduction. Radiation transpires when particles consume energy that progresses as a wave. The heat will run from the h2O to the ice continuously until the ice has absolutely melted so both elements have reached the same temperature.
Explanation:
Answer:
0.68g/ml
Explanation:
The density of an object is its mass per unit volume. It is calculated using the formula
Density = mass / volume
Mass of stopper weighed = 4.8g
The volume of stopper can be got by subtracting the (volume of water) from the (volume of water+stopper) i.e.
= 39.2ml - 32.1ml
= 7.1ml
Volume of stopper = 7.1ml
Density of stopper= 4.8/7.1
Density= 0.676056
Therefore, the density of the stopper is 0.68g/ml
Answer:
0.779 cube centimetres
Explanation:
density = mass divided by volume
rearrange the equation to solve for volume: 
plug in the corresponding values:
volume = 6.130 g / 7.87 (gcm^3)
the gs cancel, the answer will be 0.7789
we will round to three sig figs, since that's the lowest amount of figures in the given values: ~0.779 cm^3
The answer to your question would be: true
