PLEASE ANSWER ASAP!! FOR THE 2.04 EVOLUTION AND NATRUAL SELECTION LAB WHAT IS THE TEST VARIABLE AND OUTCOME VARIABLE? also my bad for the caps

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?

You can decrease the resistance of a length of wire by

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same
