When 204 g of a substance is heated to C and then plunged into a 97 g aluminum calorimeter cup containing?
En 204 g of a substance is heated to C and then plunged into a 97 g aluminum calorimeter cup containing 174 g of water at 12. C, the final temperature, as registered by a 19 g glass thermometer, is 34. C. What is the specific heat of the substance?
Answer: The heat out of the substance = heat into the cup + water + glass where q = m*c*t so 204*c*(332 - 34. 8) = 97*0. 91*(34. 8 - 12. 3) + 174*4. 2*(34. 8 - 12. 3) + 19*0. 84*(34. 8-12. 3) or 60629*c = 18788 so c = 18788/60629 = 0. 310 j/g-oc

The internal energy of a gas decreases by 204 j. How much energy transferred by heat and work done by gas?
E internal energy of a gas decreases by 204 j. A) if the process's is adiabatic, how much energy is transferred as heat? Answer in units of j. B) how much work is done on or by the gas? Answer in units of j.
Answer: 204 j of energy as work because 0 j transferred by heat in an adiabatic process's.
How long does henry's 204 roof cement take to dry?
Am going to repair a leak in my roof with henry's 204 plastic cement, and i've searched their website and read the can of course, and no where can I find how long it will take to dry. I want to test my patch but don't want to ruin the patch by getting it wet before it's had time to dry. Thanks

What does it mean when your glucose 204 but your insulin is normal?
Am in the process's of getting testing done to see if i'm polycystic(pcos) and have discovered that i'm more than likely diabetic. I see my regular Dr tomorrow. My random last week was 199, my fasting was 204. My insulin level was on the high end of normal but normal. I'm also currently trying to get pregnant. Any help would be greatly appreciated. Thanks, amanda
Answer: I agree with the previous answers, and offer an opinion on your insulin level observation. If you had blood drawn specifically for an insulin assay, and the results show that you have normal levels of insulin, then it sounds to me as though you have become insulin resistant. For whatever reason, your body's cells can no longer properly use the insulin that your pancreas makes. That is a standard type 2 diabetes scenario and is typically treated with control of your diet, increased exercise, weight loss, if appropriate, and 1 or more oral medications.
