Which statements best describe magnetic fields? Select three options. . A magnetic field is the area around a magnet where a force is exerted on certain objects. A magnetic field is an area of land where magnets are found. Magnetic field lines are strongest around the middle of the magnet. Magnetic field lines spread out of the north end of the magnet. Magnetic fields are three-dimensional and resemble a bubble.

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?
