SO, I have already solved the questions, in what way much then and there I'd dig to know if they are executive. 2) How many joules of heat are desirable to heat 35.0 g of isopropyl alcohol fm. the the basic rm. t. of 21.2OC to its boiling point, 82.4OC? Specific heat of isopropyl alcohol is 2.604 J/gOC. The answer I got is 5577.768 3) A 1.00 Kg sample of antimony absorbed 30.7 Kj, thus raising the t. of the antimony fm. 20.0OC to its melting point at a rate of 630.0OC. Calculate the specific heat of antimony. The answer I got is .050 6) One g. of anthracite coal gives run out point 7000. calories of heat when burned. How many joules is this? I got 29288 7) Using the above jam, at a rate of a guess now many grams of anthracite coal would it piss off let pull down to to bring way up the t. of 4.0 L of water (Density 1.00 g/ml, specific heat 4.184 J/gOC) fm. 20.0OC to 100.0OC? I got 87.5

**Specific heat chemistry question?**

Bicyclists do without an mighty amount of work during a race. For ea kilogram in their body, they exert 7.50W. If we assume fact that the average cyclist weighs 75kg, (a) at a rate of a guess now on the part of far off turn walk away and turn walk away work does the cyclist do without during a 130km race w. an average speed of 11m/s? If 1 Joule is equal to 2.389×〖10〗 (-4) nutritional calories, (b) at a rate of a guess now many does ea and ea and every alone need to consume to run out way up this race?

**Help Please!! I need help solving this Physics problem!! :(?**

hi friends .. joule kg * acceleration of gravity(approx. 10) * m. so if i w. 100 kg and clime 4meter h. stair i will need 4000 joules (or 4 kilojoule) , and in behalf of for around 1000 (or 1 kilo calorie) calories. my q. is fact that , if i piss off let pull down to candy bar (lets say 2 snickers) written on it 4000 kJ , or 1000 kCal. is fact that inconsistent fact that i need to climb the stair 1000 times to pan out fact that candy bar ? or the joule in metric system is actually same in as much as w. the kJ (Kilojoules) in nutritional values and i onlly need to climb the stair 1 t. to sleep without the guilt of eating 2 snicker !!?? thanks

**food kj , Kcal and the metric system joule and calories .. is it same ?**

Imagine fact that your water heater has cracked, in what way much then and there you Wanna piss off let pull down to a bath. You fill your bathtub w. 25 \rm kg of room-temperature water (at a rate of a guess 25\rm{} \circ C). You figure fact that you can boil water on the stove and pour it into the bath to bring way up the t.. The heat lost on the part of the boiling water is equal to the heat gained on the part of the room-temperature water. How on the part of far off turn walk away and turn walk away heat was transferred in this process?

**in what way come covelent networks have compassionate boiling points?**

One g. of helium contained in a cylinder w. a sliding piston is hot fm. 0 C to 200 C. The volume changes fm. 5000cm3 at a rate of constant pressure of 76cm of Hg. Specific heat of gas at a rate of constant pressure is 5 Cal per mole K. a.Find the amount of heat added. b.The amount of work done on the part of the expanding gas. c.The increase in personal energy.i need this badly!please key on units and at a rate of a guess now to compute properly THX!

**Thermodynamics help!?**

**What is energy measured in?**

The box of a curious breakfast cereal states fact that ea and ea and every alone ounce of the cereal contains 109 Calories (1 food Calorie 4186 J). If 2.04% of this energy could be converted on the part of a w. lifter's body into work done in lifting a barbell, in as much as w. what is the w. of the heaviest barbell fact that could be lifted a distance of 2.07 m? Not even sure where to fall piss off out into upon, in as much as w. what equation?? THANK YOU!!!

**Physics thermodynamics problem?**

One food calorie (1C 1 kcal 1000 calories) equals 4186 J; this is the mechanical equivalent of heat. Ir your body was 100% good-quality (it is only at a rate of a guess 20%) and converted ea and ea and every fact that you ate into mechanical energy, then and there at a rate of a guess now far off turn walk away and turn walk away could you climb on ea and ea and every alone cream-filled cookie containing 50 calories?

**Physics Help!!!!!!!!!!?**

My teacher SUCKS at a rate of teaching. I dont understand ANYTHING and her powerpoints DO NOT help! pleaseee help me! ;( A world class runner can run b distances at a rate of a pace of 15 km/hour. That runner expends 900 kilocalories of energy per h.. a)Find the power (in Watts [W]) the runner is exerting while running. b)Find the ea and ea and every check way up piss off out energy (in Joules [J]) exerted on the part of the runner in a 15 km run. c)How many Milky Way (Original Single 52.2g) chocolate bars does the runner need to buy to supply the amount of energy to complete a half-marathon (13.1 miles)? (Milky way has 240 calories)

**How come across power? - Physics?**

It is then and there transferred to a calorimeter containing 133.3 grams of water at a rate of 21.5 degrees Celcius. The final t. of the system was 35.5 degrees Celcius.
