How much heat energy in megajoules is neede to convert 7kilograms of ice at negative 9 degrees to water at 0 degrees celsius
den301095 [7]

Heat_1: Get the ice to 0 degrees

Convert 7 kg to grams

7 kg [1000 grams / 1 kg] = 7000 grams

Heat needed to get the the ice from - 9 to 0

deltat = 0 - -9 = 9 degrees

m = 7000 grams

c = 2.1 joules/gram

Heat_1 = m*c*deltat

Heat_1 = 7000 * 2.1 * 9

Heat_1 = 132,300 joules

Heat_2: Melt the ice.

There is no temperature change. The formula is 333 j/gram

Formula: H = mass * constant

H = 7000 g * 333 J / gram

H = 2331000 joules

Heat_3: Total amount of Joules needed.

2331000 + 132300 = 2 463 300 joules

Convert to Megajoules

2 463 300 joules * 1 megajoule / 1000000 = 2.63 megajoules.

If a girl is dating a guy and the guy is a catfish, what should the girl do to prove it?
dolphi86 [110]

The girl should first prevent getting scammed. She shouldn’t be sharing any personal information about herself or anybody else. Then to try to prove, she can maybe ask to face time during the day, or asks him out to go somewhere(park,movies,etc.,) but make sure you take someone with you like a trusted adult or someone older, and if he keeps making excuses and denying then it’s pretty clear it’s a catfish.
