HEL ME Waters density is 1 g/cm^3. Glass has a density of 2.8 g/cm^3. Will glass float in water?
YES, it will float because its density is greater than the density of water/

This question cannot be answered because density does not determine buoyancy

NO, it will not float because its density is greater than the density of water

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

its first and third is your answer i did the qustion the fourth isnt right

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
