Mr. harris assigned his class the task to identify and order unknown liquids by their specific heat. four liquids are heated at the same temperature setting for ten minutes. the temperature change of each sample is recorded in the table above. order the unknown liquid samples by specific heat from lowest to highest. temperature change of liquid samples sample mass (grams) start temperature (°c) ending temperature (°c) 1 200 23 69 2 200 20 67 3 200 21 65 4 200 22 70

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
