The closest spread to peanut butter I've found in terms of flavor and texture is sunflower seed butter. It's also relatively easy to find; I've seen it in large chain grocery stores right next to the peanut butter.
A curmudgeon with years of practice. The bubbles in boiling water are steam or vaporized water. The bubbles initially do not reach the surface of the billing fluid as the colder water away from the hot bottom cools the steam turning it back to liquid. WHen all the water is at 100oC the bubbles reach the top.
Water boils to make the pressure in the bubbles that are formed by the application of heat equalize with the atmospheric pressure. Water makes this happen at its boiling point. This boiling point of water differs based on the height at which the water must vaporize.ater boils to change its liquid state to a gaseous state, which is called water vapor. When water changes from a liquid form to a vapor form it takes up some energy. This energy is called the latent heat of evaporation.
