1-86 The specific heats of some elements at 25oC are as follows: aluminum = 0.215 cal/g · oC; carbon (graphite) = 0.170 caI/g oC; iron = 0.107 cal/g mercury = 0.033 1 caI/g oC. (a) Which element would require the smallest amount of heat to raise the temperature of 100 g of the element by 10oC? (b) If the same amount of heat needed to raise the temperature of 1 g of aluminum by 25oC were applied to 1 g of mercury, by how many degrees would its temperature be raised? (c) If a certain amount of heat is used to raise the temperature of 1.6 g of iron by 10oC, the temperature of 1 g of which element would also be raised by 10oC, using the same amount of heat?
Washington, D.C. has an average January temperature of 34.9 degrees Fahrenheit. What is this average if temp is expressed in Celsius? (Round to two decimal places.) [Hint: Conversion between Fahrenheit and Celsius is a linear transformation: Fahrenheit = Celsius*1.80 + 32, or Celsius = Fahrenheit*(1/1.80) - (32/1.80)]
1. It is known that the boiling point of water on the Kelvin temperature scale is 373.15 K and the freezing temperature of water is 273.15 K. A temperature scale, called the Reaumur (R) scale, is defined by identifying the freezing point of water as 0.0°R and the boiling point of water as 80.0°R. What is 62.3°R on the Kelvin scale? Clearly define your variables.
A student sets up the following equation to convert a measurement. (The ? stands for a number the student is going to calculate.) Fill in the missing part of this equation. Note: your answer should be in the form of one or more fractions multiplied together. -7.5 × 105 J mmol. °C M = ? kJ mol. °C ☐x10 X μ 010
Normal body temperature is 98.4°F. Use your Celsius temperature from the above question (81) to calculate this temperature in Kelvin. To determine the conversion factors (if you can’t remember them), use the following: Freezing point of water = 0 oC = 273.15 K. Boiling point of water = 100 oC = 373.15 K. Use the correct number of significant figures in your answers.
A Chemistry 20 student uses a thermometer and a hot plate and measures the boiling point of ethyl alcohol to be 74.1 ºC. Then, she looks in a reference book and finds that the actual boiling point of ethyl alcohol is 78.4 ºC. What is her percent error?Record only your final answer with the correct number of significant digits and the proper units.

Calculate the electrostatic force of repulsion for two protons separated by 93.0 pm. The charge of a proton is q = 1.6 x 10-1⁹ C. Express your answer to two significant figures and include the appropriate units. Fel = μA 2.7.10 6 Submit N Previous Answers Request Answer ? X Incorrect; Try Again; 5 attempts remaining Use the equation Fel = K(Q₁ Q₂/d²) to find the electrostatic force between the two particles. Q₁ and Q2 are the charges on the particles (charge of a proton here), and d is the distance of separation. The constant is given in the introduction and has the units Nm²/C². This means that the distance must be converted from picometers to meters using the relation 1 pm = 1 × 10¯ m. -12
Convert 6.4 x 10^-28 j-s/ kg to erg- min /lb. Note that “j” means “ joule” - it is one of the units used for energy and “j-s” means “ joules times seconds” not minus. While solving this problem please follow the same three steps and write down the details of each step.
