Yes, you can place pothos outdoors in summer; however, be sure to locate it where it will not be in the direct sun during the hottest part of the day. In other words, morning sun no afternoon sun, as this could quickly scorch the plant.
You can put pothos - sometimes known as devils ivy - outside, but only IN THE SHADE. Indoor plants are like indoor people - they have no defense against the sun, and will sunburn horribly within a couple of hours. Just make sure you water LOTS, because outdoors the plant will use 10 times more water than it did inside.
