(i) The density of the solid is 950 kg/m³
(ii) the density of another liquid in which the same solid would float is 200 kg/m³
The given parameters;
mass of the solid in air, Ma = 237.5 g
mass of the solid in liquid, Ms = 12.5 g
density of the liquid,
(i) The density of the solid is calculated as follows;
Weight in air - Weight in liquid = upthrust
(ii) the density of another liquid in which the same solid would float with one-fifth of its volume exposed above the liquid surface.
This is a low density liquid, because one-fifth of the solid is above the liquid surface while four-fifth is below the liquid surface.
the specific gravity of the liquid = ¹/₅ = 0.2
density of water ,
Thus, the density of another liquid in which the same solid would float is 200 kg/m³

Answer:
physical property
Explanation: Some substances exist as gases at room temperature (oxygen and carbon dioxide), while others, like water and mercury metal, exist as liquids.
Because trees get thier nutrients and energy from the sun. They absorb it through the leaves and it makes them grow strong. then someone cuts down the tree and makes the wood for your fire. So, the fire burns the wood that was made from the tree that got nutrients and grew from the sun.
exothermic
Explanation:
negative means it's losing energy
A) seems more likely and work in unity.
