Asample of urea is placed in the reaction vessel of a bomb calorimeter. the temperatures measured before and after combustion are 23.56◦c and 25.34◦c, respectively. if the heat sink is 100 ml of water and the calorimeter’s heat capacity is 45 j/k, what is the change in internal energy in the combustion of the sample of urea?

i think i backed my dad

a true.

explanation:

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
