How will the candle contributes to the pressure and temperature of gases inside the glass?
The candle contributes to the pressure and temperature of the gases inside the glass because of the increasing temperature the lit of the candle disposes into the gas molecules inside and as these gas molecules rise in temperature they become unsettling and since heat makes gas molecules robust the area becomes smaller for them to be ecstatic and as the dynamics is explained p=f/a the pressure increases.

Answer:
1.The Aluminum block
2.its surroundings absorb energy from it.
Explanation:
In this question it is important to remember that density of an object is the mass of that object divided by its volume.
The expression applied here is density=mass/volume
Given that the mass is constant,lets say mass= m=1g
and density of aluminum=2.7g/cm³ and that of iron is 7.8 g/cm³ then volume=?
Volume=mass/density
Volume of aluminum= 1/2.7 =0.3704 cm³
Volume of iron = 1/7.8 =0.1282 cm³
Here we see volume of Aluminum block is the largest.
2.As water in an ice cube tray freezes, its surroundings absorb energy from it.When the water freezes, latent heat of freezing is given out to the surrounding.When water is freezing, it stays at a constant temperature of 0°C, the heat energy released ensures that there is no cooling past 0 °C.
